feat: admin soft-delete and hard-delete for books

- Add `archived` bool to domain.BookMeta, pbBook, and Meilisearch bookDoc
- ArchiveBook / UnarchiveBook patch the PocketBase record; ListBooks filters
  archived=false so hidden books disappear from all public responses
- Meilisearch: add `archived` as a filterable attribute; Search and Catalogue
  always prepend `archived = false` to exclude archived books from results
- DeleteBook permanently removes the PocketBase record, all chapters_idx rows,
  MinIO chapter objects, cover image, and the Meilisearch document
- New BookAdminStore interface with ArchiveBook, UnarchiveBook, DeleteBook
- Admin HTTP endpoints: PATCH /api/admin/books/{slug}/archive|unarchive,
  DELETE /api/admin/books/{slug}
- PocketBase schema: archived field added to live pb.libnovel.cc and to
  pb-init-v3.sh (both create block and add_field migration)

-# iOS UI/UX Skill — LibNovel
-
-Load this skill whenever working on SwiftUI views in `ios/`. It defines design standards, review process for screenshots, and implementation rules.
-
----
-
-## Screenshot Review Process
-
-When the user provides a screenshot of the app:
-
-1. **Analyze first** — identify specific UI/UX issues across these categories:
-   - Visual hierarchy and spacing
-   - Typography (size, weight, contrast)
-   - Color and material usage
-   - Animation and interactivity gaps
-   - Accessibility problems
-   - Deprecated or non-native patterns
-2. **Present a numbered list** of suggested improvements with brief rationale for each.
-3. **Ask for confirmation** before writing any code: "Should I apply all of these, or only specific ones?"
-4. Apply only what the user confirms.
-
----
-
-## Design System
-
-### Colors & Materials
-- **Accent**: `Color.amber` (project-defined). Use for active state, selection indicators, progress fills, and CTAs.
-- **Backgrounds**: Prefer `.regularMaterial`, `.ultraThinMaterial`, or `.thinMaterial` over hard-coded `Color.black.opacity(x)` or `Color(.systemBackground)`.
-- **Dark overlays** (e.g. full-screen players): Use `KFImage` blurred background + `Color.black.opacity(0.5–0.6)` overlay. Never use a flat solid black background.
-- **Semantic colors**: Use `.primary`, `.secondary`, `.tertiary` foreground styles. Avoid hard-coded `Color.white` except on dark material contexts (full-screen player).
-- **No hardcoded color literals** — use `Color+App.swift` extensions or system semantic colors.
-
-### Typography
-- Use the SF Pro system font via `.font(.title)`, `.font(.body)`, etc. — never hardcode font names except for intentional stylistic accents (e.g. "Snell Roundhand" for voice watermark).
-- Apply `.fontWeight()` and `.fontDesign()` modifiers rather than custom font families.
-- Support Dynamic Type — never hardcode a fixed font size as the sole option without a `.minimumScaleFactor` or system font size modifier.
-- Hierarchy: title3.bold for primary labels, subheadline for secondary, caption/caption2 for metadata.
-
-### Spacing & Layout
-- Minimum touch target: **44×44 pt**. Use `.frame(minWidth: 44, minHeight: 44)` or `.contentShape(Rectangle())` on small icons.
-- Prefer 16–20 pt horizontal padding on full-width containers; 12 pt for compact inner elements.
-- Use `VStack(spacing:)` and `HStack(spacing:)` explicitly — never rely on default spacing for production UI.
-- Corner radii: 12–14 pt for cards/chips, 10 pt for small badges, 20–24 pt for large cover art.
-
----
-
-## Animation Rules
-
-### Spring Animations (default for all interactive transitions)
-- Use `.spring(response:dampingFraction:)` for state-driven layout changes, selection feedback, and appear/disappear transitions.
-- Recommended defaults:
-  - Interactive elements: `response: 0.3, dampingFraction: 0.7`
-  - Entrance animations: `response: 0.45–0.5, dampingFraction: 0.7`
-  - Quick snappy feedback: `response: 0.2, dampingFraction: 0.6`
-- Reserve `.easeInOut` only for non-interactive, ambient animations (e.g. opacity pulses, generating overlays).
-
-### SF Symbol Transitions
-- Always use `contentTransition(.symbolEffect(.replace.downUp))` when a symbol name changes based on state (play/pause, checkmark/circle, etc.).
-- Use `.symbolEffect(.variableColor.cumulative)` for continuous animations (waveform, loading indicators).
-- Use `.symbolEffect(.bounce)` for one-shot entrance emphasis (e.g. completion checkmark appearing).
-- Use `.symbolEffect(.pulse)` for error/warning states that need attention.
-
-### Repeating Animations
-- Use `phaseAnimator` for any looping animation that previously used manual `@State` + `withAnimation` chains.
-- Do not use `Timer` publishers for UI animation — prefer `phaseAnimator` or `TimelineView`.
-
----
-
-## Haptic Feedback
-
-Add `UIImpactFeedbackGenerator` to every user-initiated interactive control:
-- `.light` — toggle switches, selection chips, secondary actions, slider drag start.
-- `.medium` — primary transport buttons (play/pause, chapter skip), significant confirmations.
-- `.heavy` — destructive actions (only if no confirmation dialog).
-
-Pattern:
-```swift
-Button {
-    UIImpactFeedbackGenerator(style: .light).impactOccurred()
-    // action
-} label: { ... }
-```
-
-Do **not** add haptics to:
-- Programmatic state changes not directly triggered by a tap.
-- Buttons inside `List` rows that already use swipe actions.
-- Scroll events.
-
----
-
-## iOS 17+ API Usage
-
-Flag and replace any of the following deprecated patterns:
-
-| Deprecated | Replace with |
-|---|---|
-| `NavigationView` | `NavigationStack` |
-| `@StateObject` / `ObservableObject` (new types only) | `@Observable` macro |
-| `DispatchQueue.main.async` | `await MainActor.run` or `@MainActor` |
-| Manual `@State` animation chains for repeating loops | `phaseAnimator` |
-| `.animation(_:)` without `value:` | `.animation(_:value:)` |
-| `AnyView` wrapping for conditional content | `@ViewBuilder` + `Group` |
-
-Do **not** refactor existing `ObservableObject` types to `@Observable` unless explicitly asked — only apply `@Observable` to new types.
-
----
-
-## Accessibility
-
-Every view must:
-- Support VoiceOver: add `.accessibilityLabel()` to icon-only buttons and image views.
-- Support Dynamic Type: test that text doesn't truncate at xxxLarge without a layout adjustment.
-- Meet contrast ratio: text on tinted backgrounds must be legible — avoid `.opacity(0.25)` or lower for any user-readable text.
-- Touch targets ≥ 44pt (see Spacing above).
-- Interactive controls must have `.accessibilityAddTraits(.isButton)` if not using `Button`.
-- Do not rely solely on color to convey state — pair color with icon or label.
-
----
-
-## Performance
-
-- **Isolate high-frequency observers**: Any view that observes a `PlaybackProgress` (timer-tick updates) must be a separate sub-view that `@ObservedObject`-observes only the progress object — not the parent view. This prevents the entire parent from re-rendering every 0.5 seconds.
-- **Avoid `id()` overuse**: Only use `.id()` to force view recreation when necessary (e.g. background image on track change). Prefer `onChange(of:)` for side effects.
-- **Lazy containers**: Use `LazyVStack` / `LazyHStack` inside `ScrollView` for lists of 20+ items. `List` is inherently lazy and does not need this.
-- **Image loading**: Always use `KFImage` (Kingfisher) with `.placeholder` for remote images. Never use `AsyncImage` for cover art — it has no disk cache.
-- **Avoid `AnyView`**: It breaks structural identity and hurts diffing. Use `@ViewBuilder` or `Group { }` instead.
-
----
-
-## Offline & Error States
-
-Every view that makes network calls must:
-1. Wrap the body in a `VStack` with `OfflineBanner` at the top, gated on `networkMonitor.isConnected`.
-2. Suppress network errors silently when offline via `ErrorAlertModifier` — do not show an alert when the device is offline.
-3. Gate `.task` / `.onAppear` network calls: `guard networkMonitor.isConnected else { return }`.
-4. Show a non-blocking inline empty state (not a full-screen error) for failed loads when online.
-
----
-
-## Component Checklist (before submitting any view change)
-
-- [ ] All interactive elements ≥ 44pt touch target
-- [ ] SF Symbol state changes use `contentTransition(.symbolEffect(...))`
-- [ ] State-driven layout transitions use `.spring(response:dampingFraction:)`
-- [ ] Tappable controls have haptic feedback
-- [ ] No `NavigationView`, no `DispatchQueue.main.async`, no `.animation(_:)` without `value:`
-- [ ] High-frequency observers are isolated sub-views
-- [ ] Offline state handled with `OfflineBanner` + `NetworkMonitor`
-- [ ] VoiceOver labels on icon-only buttons
-- [ ] No hardcoded `Color.black` / `Color.white` / `Color(.systemBackground)` where a material applies

+
+## CI/CD — Gitea Actions
+
+- Workflows live in `.gitea/workflows/` — **not** `.github/workflows/`
+- Self-hosted Gitea instance; use `gitea.ref_name` / `gitea.sha` (not `github.*`)
+- Two workflows:
+  - `ci.yaml` — runs on every push to `main` (test + type-check)
+  - `release.yaml` — runs on `v*` tags (build Docker images, upload source maps, create Gitea release)
+- Secrets: `DOCKER_USER`, `DOCKER_TOKEN`, `GITEA_TOKEN`, `GLITCHTIP_AUTH_TOKEN`
+
+### Git credentials
+
+Credentials are embedded in the remote URL — no `HOME=/root` or credential helper needed for push:
+
+```
+https://kamil:95782641Apple%24@gitea.kalekber.cc/kamil/libnovel.git
+```
+
+All git commands still use `HOME=/root` prefix for consistency (picks up `/root/.gitconfig` for user name/email), but push auth works without it.
+
+### Releasing a new version
+
+```bash
+HOME=/root git tag v2.6.X -m "Short title"
+HOME=/root git push origin v3-cleanup --tags
+```
+
+CI will build all Docker images, upload source maps to GlitchTip, and create a Gitea release automatically.
+
+---
+
+## GlitchTip Error Tracking
+
+- Instance: `https://errors.libnovel.cc/`
+- Org: `libnovel`
+- Projects: `ui` (id/1), `backend` (id/2), `runner` (id/3)
+- Tool: `glitchtip-cli` v0.1.0
+
+### Per-service DSNs (stored in Doppler)
+
+| Service | Doppler key | GlitchTip project |
+|---|---|---|
+| UI (SvelteKit) | `PUBLIC_GLITCHTIP_DSN` | ui (1) |
+| Backend (Go) | `GLITCHTIP_DSN_BACKEND` | backend (2) |
+| Runner (Go) | `GLITCHTIP_DSN_RUNNER` | runner (3) |
+
+### Source map upload flow (release.yaml)
+
+The correct order is **critical** — uploading before `releases new` results in 0 files shown in GlitchTip UI:
+
+```
+glitchtip-cli sourcemaps inject ./build          # inject debug IDs
+glitchtip-cli releases new <version>             # MUST come before upload
+glitchtip-cli sourcemaps upload ./build \
+  --release <version>                            # associate files with release
+glitchtip-cli releases finalize <version>        # mark release complete
+```
+
+---
+
+## Infrastructure
+
+| Environment | Host | Path | Doppler config |
+|---|---|---|---|
+| Prod | `165.22.70.138` | `/opt/libnovel/` | `prd` |
+| Homelab runner | `192.168.0.109` | `/opt/libnovel-runner/` | `prd_homelab` |
+
+### Docker Compose — always use Doppler
+
+```bash
+# Prod
+doppler run --project libnovel --config prd -- docker compose <cmd>
+
+# Homelab full-stack (runs from .bak file on server)
+doppler run --project libnovel --config prd_homelab -- docker compose -f homelab/docker-compose.yml.bak <cmd>
+
+# Homelab runner only
+doppler run --project libnovel --config prd_homelab -- docker compose -f homelab/runner/docker-compose.yml <cmd>
+```
+
+- Prod runner has `profiles: [runner]` — `docker compose up -d` will NOT accidentally start it
+- When deploying, always sync `docker-compose.yml` to the server before running `up -d`
+- **Caddyfile is NOT in git** — lives at `/opt/libnovel/Caddyfile` on prod server only. Edit directly on the server and restart the `caddy` container.
+
+---
+
+## Observability
+
+| Tool | Purpose |
+|---|---|
+| GlitchTip | Error tracking (UI + backend + runner) |
+| Grafana Faro | RUM / Web Vitals (collector at `faro.libnovel.cc/collect`) → Alloy (port 12347) |
+| OpenTelemetry | Distributed tracing (OTLP → cloudflared → OTel collector → Tempo) |
+| Grafana | Dashboards at `https://grafana.libnovel.cc` |
+
+### Grafana dashboards: `homelab/otel/grafana/provisioning/dashboards/`
+
+Key dashboards:
+- `backend.json` — Backend logs (Loki: `{service_name="backend"}`, plain text)
+- `runner.json` — Runner logs (Loki: `{service_name="runner"}`) + Asynq Prometheus metrics
+- `web-vitals.json` — Web Vitals (Loki: `{service_name="unknown_service"} kind=measurement` + pattern parser)
+- `catalogue.json` — Scrape progress (Loki: `{service_name="runner"} | json | body="..."`)
+
+### Data pipeline (2026-04-07 working state)
+
+**Browser → Grafana Faro:**
+Browser sends RUM data → `https://faro.libnovel.cc/collect` → **Alloy** `faro.receiver` (port 12347) → Loki (logs/exceptions) + OTel collector → **Tempo** (traces)
+
+**Backend/Runner → OTel:**
+Backend/Runner Go SDK → `https://otel.libnovel.cc` (cloudflared tunnel) → **OTel collector** (port 4318) → Tempo (traces) + Loki (logs via `otlphttp/loki` exporter)
+Runner also sends to **Alloy** `otelcol.receiver.otlp` (port 4318) → `otelcol.exporter.loki` → Loki
+
+### Loki log format per service
+
+- `service_name="backend"`: Plain text (e.g. `backend: asynq task dispatch enabled`)
+- `service_name="runner"`: JSON with `body`, `attributes{slug,chapters,page}`, `severity`
+- `service_name="unknown_service"`: Faro RUM text format (e.g. `kind=measurement lcp=5428.0 ...`)
+
+### OTel Collector ports (homelab)
+
+- gRPC: `4317` — receives from cloudflared (`otel.libnovel.cc`)
+- HTTP: `4318` — receives from cloudflared + Alloy
+- Metrics: `8888`
+
+### Known issues / pending fixes
+
+- Web Vitals use `service_name="unknown_service"` (Faro SDK doesn't set service.name in browser) — works with `unknown_service` label
+- Runner logs go to both Alloy→Loki AND OTel collector→Loki (dual pipeline — intentional for resilience)
+
+---
+
+## Go Backend
+
+- Primary files: `orchestrator.go`, `server/handlers_*.go`, `novelfire/scraper.go`, `storage/hybrid.go`, `storage/pocketbase.go`
+- Store interface: `store.go` — never touch MinIO/PocketBase clients directly outside `storage/`
+- Two binaries built from the same module: `backend` (HTTP API) and `runner` (Asynq worker)
+
+---
+
+## SvelteKit UI
+
+- Source: `ui/src/`
+- i18n: Paraglide — translation files in `ui/messages/*.json` (5 locales)
+- Auth debug bypass: `GET /api/auth/debug-login?token=<DEBUG_LOGIN_TOKEN>&username=<username>&next=<path>`
+
+---
+
+## iOS App
+
+Full context in `ios/AGENTS.md`. Quick notes:
+- SwiftUI, iOS 17+, `@Observable` for new types
+- Download key separator: `::` (not `-`)
+- Voice fallback: book override → global default → `"af_bella"`
+- Offline pattern: `NetworkMonitor` env object + `OfflineBanner` + `ErrorAlertModifier`

+# Paraglide JS Compiled Output
+
+> Auto-generated i18n message functions. Import `messages.js` to use translated strings.
+
+Compiled from: `/opt/libnovel-v3/ui/project.inlang`
+
+
+## What is this folder?
+
+This folder contains compiled [Paraglide JS](https://github.com/opral/paraglide-js) output. Paraglide JS compiles your translation messages into tree-shakeable JavaScript functions.
+
+## At a glance
+
+Purpose:
+- This folder stores compiled i18n message functions.
+- Source translations live outside this folder in your inlang project.
+
+Safe to import:
+- `messages.js` — all message functions
+- `runtime.js` — locale utilities
+- `server.js` — server-side middleware
+
+Do not edit:
+- All files in this folder are auto-generated.
+- Changes will be overwritten on next compilation.
+
+```
+paraglide/
+├── messages.js      # Message exports (import this)
+├── messages/        # Individual message functions
+├── runtime.js       # Locale detection & configuration
+├── registry.js      # Formatting utilities (plural, number, datetime)
+├── server.js        # Server-side middleware
+└── .gitignore       # Marks folder as generated
+```
+
+## Usage
+
+```js
+import * as m from "./paraglide/messages.js";
+
+// Messages are functions that return localized strings
+m.hello_world();             // "Hello, World!" (in current locale)
+m.greeting({ name: "Sam" }); // "Hello, Sam!"
+
+// Override locale per-call
+m.hello_world({}, { locale: "de" });           // "Hallo, Welt!"
+m.greeting({ name: "Sam" }, { locale: "de" }); // "Hallo, Sam!"
+```
+
+## Runtime API
+
+```js
+import { getLocale, getTextDirection, setLocale, locales, baseLocale } from "./paraglide/runtime.js";
+
+getLocale();    // Current locale, e.g., "en"
+getTextDirection(); // "ltr" | "rtl" for current locale
+setLocale("de"); // Set locale
+locales;        // Available locales, e.g., ["en", "de", "fr"]
+baseLocale;     // Default locale, e.g., "en"
+```
+
+## Strategy
+
+The strategy determines how the current locale is detected and persisted:
+
+- **Cookie**: Stores locale preference in a cookie.
+- **URL**: Derives locale from URL patterns (e.g., `/en/about`, `en.example.com`).
+- **GlobalVariable**: Uses a global variable (client-side only).
+- **BaseLocale**: Always returns the base locale.
+
+Strategies can be combined. The order defines precedence:
+
+```js
+await compile({
+  project: "./project.inlang",
+  outdir: "./src/paraglide",
+  strategy: ["url", "cookie", "baseLocale"],
+});
+```
+
+See the [strategy documentation](https://inlang.com/m/gerre34r/library-inlang-paraglideJs/strategy) for details.
+
+## Markup (Rich Text)
+
+Messages can contain markup tags for bold, links, and other inline elements. Translators control where tags appear; developers control how they render.
+
+### Message syntax
+
+```json
+{
+  "cta": "{#link to=|/docs|}Read the docs{/link}",
+  "bold_text": "This is {#bold}important{/bold}"
+}
+```
+
+- `{#tagName}` opens a tag, `{/tagName}` closes it.
+- Options: `to=|/docs|` (accessed via `options.to`).
+- Attributes: `@track` (boolean, accessed via `attributes.track`).
+
+This is the default inlang message syntax. Paraglide's message format is plugin-based — you can use [ICU MessageFormat 1](https://inlang.com/m/p7c8m1d2/plugin-inlang-icu-messageformat-1), [i18next](https://inlang.com/m/3i8bor92/plugin-inlang-i18next), or other [plugins](https://inlang.com/c/plugins) instead.
+
+### Rendering markup
+
+Calling `m.cta()` returns **plain text** (markup stripped). To render markup, use the framework adapter or the low-level `parts()` API:
+
+```js
+const parts = m.cta.parts({});
+// [
+//   { type: "markup-start", name: "link", options: { to: "/docs" }, attributes: {} },
+//   { type: "text", value: "Read the docs" },
+//   { type: "markup-end", name: "link" }
+// ]
+```
+
+Framework adapters provide a `<ParaglideMessage>` component that accepts markup renderers:
+
+- `@inlang/paraglide-js-react`
+- `@inlang/paraglide-js-vue`
+- `@inlang/paraglide-js-svelte`
+- `@inlang/paraglide-js-solid`
+
+```jsx
+import { ParaglideMessage } from "@inlang/paraglide-js-react"; // or -vue, -svelte, -solid
+
+<ParaglideMessage
+  message={m.cta}
+  inputs={{}}
+  markup={{
+    link: ({ children, options }) => <a href={options.to}>{children}</a>,
+  }}
+/>
+```
+
+See the [markup documentation](https://inlang.com/m/gerre34r/library-inlang-paraglideJs/markup) for details.
+
+## Key concepts
+
+- **Tree-shakeable**: Each message is a function, enabling [up to 70% smaller i18n bundle sizes](https://inlang.com/m/gerre34r/library-inlang-paraglideJs/benchmark) than traditional i18n libraries.
+- **Typesafe**: Full TypeScript/JSDoc support with autocomplete.
+- **Variants**: Messages can have variants for pluralization, gender, etc.
+- **Fallbacks**: Missing translations fall back to the base locale.
+
+## Links
