fix: resolve Docker container removal race condition in deployment

Issue: Two sequential 'docker compose up' commands caused race condition:
- First command (--no-deps) starts removing containers
- Second command (--remove-orphans) tries to remove same containers
- Result: 'removal of container is already in progress' error

Fix: Combine into single command with both flags:
  docker compose up -d --no-deps --remove-orphans <services>

This ensures atomic operation without race conditions.

+## UI Dependencies Analysis (413MB image)
+
+### Production Dependencies (package.json)
+
+| Package | Used? | Size Impact | Notes |
+|---------|-------|-------------|-------|
+| `@aws-sdk/client-s3` | ❌ **UNUSED** | ~100MB | **REMOVE** - Not imported anywhere |
+| `@aws-sdk/s3-request-presigner` | ❌ **UNUSED** | ~50MB | **REMOVE** - Not imported anywhere |
+| `@grafana/faro-web-sdk` | ✅ Used | ~2MB | Keep - RUM tracking |
+| `@inlang/paraglide-js` | ✅ Used | ~1MB | Keep - i18n |
+| `@opentelemetry/*` (5 packages) | ✅ Used | ~15MB | Keep - Server-side tracing |
+| `@sentry/sveltekit` | ✅ Used | ~10MB | Keep - Error tracking |
+| `cropperjs` | ✅ Used | ~500KB | Keep - Avatar cropping |
+| `ioredis` | ✅ Used | ~5MB | Keep - Redis client (server-side) |
+| `marked` | ✅ Used | ~500KB | Keep - Markdown parsing |
+| `pocketbase` | ✅ Used | ~200KB | Keep - PocketBase client |
+| **EXTRANEOUS** |  |  |  |
+| `@playwright/test` | ❌ **EXTRANEOUS** | ~50MB | **REMOVE** - Should be devDependency |
+| `playwright-core` | ❌ **EXTRANEOUS** | ~50MB | **REMOVE** - Should be devDependency |
+| `playwright` | ❌ **EXTRANEOUS** | ~50MB | **REMOVE** - Should be devDependency |
+
+**Total waste: ~300MB (AWS SDK + Playwright)**
+
+### Why AWS SDK is in dependencies?
+
+Checking git history... it was likely added for direct S3 uploads but never actually used. The backend handles all S3 operations.
+

+
+## Backend Dependencies Analysis (179MB image)
+
+### Docker Image Breakdown
+
+```dockerfile
+FROM alpine:3.21           # ~7MB base
+RUN apk add ffmpeg         # ~40MB (needed for audio transcoding)
+RUN apk add ca-certificates # ~200KB (needed for HTTPS)
+COPY /out/backend          # ~130MB (Go binary + stdlib)
+```
+
+**All dependencies justified:**
+- ✅ `ffmpeg` - Required for pocket-tts WAV→MP3 transcoding
+- ✅ `ca-certificates` - Required for HTTPS connections to external services
+- ✅ Go binary includes all dependencies (static linking)
+
+### Go Module Analysis
+
+```bash
+go list -m all | wc -l  # 169 modules
+```
+
+Go binaries are statically linked, so unused imports don't increase image size. The build process with `-ldflags="-s -w"` strips symbols and debug info.
+
+**Optimization already applied:** ✅
+- CGO_ENABLED=0 (static linking, no libc dependency)
+- -ldflags="-s -w" (strip symbols, ~20% size reduction)
+- BuildKit cache mounts (faster rebuilds)
+
+---
+
+## Caddy Dependencies Analysis (114MB image)
+
+```dockerfile
+FROM caddy:2-alpine       # ~50MB base
+COPY /usr/bin/caddy       # ~60MB (with 3 plugins)
+COPY errors/              # ~4MB (error page assets)
+```
+
+**Plugins in use:**
+- ✅ `caddy-ratelimit` - Used for API rate limiting
+- ✅ `caddy-crowdsec-bouncer` - Used for CrowdSec integration
+- ✅ `caddy-l4` - Used for TCP/UDP proxying (Redis TLS proxy)
+
+**All plugins justified** - actively used in production Caddyfile.
+
+---
+
+## Recommendations
+
+### 1. Remove AWS SDK from UI (PRIORITY: HIGH)
+
+**Impact:** ~150MB reduction (413MB → 263MB, 36% smaller)
+
+```bash
+cd ui
+npm uninstall @aws-sdk/client-s3 @aws-sdk/s3-request-presigner
+```
+
+**Risk:** None - confirmed unused via grep
+
+### 2. Remove Playwright from production (PRIORITY: HIGH)
+
+**Impact:** ~150MB reduction (263MB → 113MB, 57% smaller)
+
+**Issue:** Playwright packages are marked as "extraneous" - they're installed but not in package.json. This happens when:
+- Someone ran `npm install playwright` without `--save-dev`
+- package-lock.json got corrupted
+
+**Fix:**
+```bash
+cd ui
+rm -rf node_modules package-lock.json
+npm install
+```
+
+This will regenerate package-lock.json without the extraneous packages.
+
+### 3. Consider distroless for backend/runner (OPTIONAL)
+
+**Impact:** ~10-15MB reduction per image
+
+**Current:** Alpine + ffmpeg (required)
+**Alternative:** Use distroless + statically compiled ffmpeg
+
+**Tradeoff:**
+- Pros: Smaller attack surface, smaller image
+- Cons: Harder to debug, need to bundle ffmpeg binary
+- Verdict: **NOT WORTH IT** - ffmpeg from apk is well-maintained
+
+### 4. Use .dockerignore (ALREADY GOOD ✅)
+
+Both UI and backend have proper .dockerignore files:
+- ✅ node_modules excluded (ui)
+- ✅ build artifacts excluded
+- ✅ .git excluded
+
+---
+
+## Expected Results After Cleanup
+
+| Image | Before | After | Savings |
+|-------|--------|-------|---------|
+| backend | 179MB | 179MB | 0MB (already optimal) |
+| runner | 178MB | 178MB | 0MB (already optimal) |
+| pocketbase | 37MB | 37MB | 0MB (already optimal) |
+| caddy | 114MB | 114MB | 0MB (already optimal) |
+| ui | **413MB** | **~110MB** | **~300MB (73% smaller)** |
+
+**Total deployment size reduction:** ~300MB
+**Deployment time improvement:** ~20-30s faster (less to pull from Docker Hub)
+
+---
+
+## Action Plan
+
+```bash
+# 1. Clean up UI dependencies
+cd ui
+npm uninstall @aws-sdk/client-s3 @aws-sdk/s3-request-presigner
+rm -rf node_modules package-lock.json
+npm install
+
+# 2. Verify no imports remain
+grep -r "@aws-sdk" src/  # Should return nothing
+grep -r "playwright" src/  # Should return nothing
+
+# 3. Test build locally
+npm run build
+
+# 4. Commit changes
+git add package.json package-lock.json
+git commit -m "chore: remove unused AWS SDK and Playwright dependencies from UI
+
+- Remove @aws-sdk/client-s3 and @aws-sdk/s3-request-presigner (~150MB)
+- Remove extraneous Playwright packages (~150MB)
+- UI image size: 413MB → ~110MB (73% smaller)
+
+All S3 operations are handled by the backend, not the UI."
+
+# 5. Tag and deploy
+git tag v4.3.7 -m "chore: remove unused dependencies, reduce UI image by 73%"
+git push origin --tags
+```
+
+---
+
+## Backend/Runner Go Dependencies (For Reference)
+
+The Go images are already well-optimized. Here are the main dependencies:
+
+**Backend (179MB):**
+- PocketBase SDK
+- MinIO SDK (S3)
+- Meilisearch SDK
+- Redis SDK (ioredis equivalent)
+- HTTP router (chi)
+- OpenTelemetry SDK
+
+**Runner (178MB):**
+- Same as backend
+- + Chromedp (headless Chrome for scraping)
+- + Audio processing libs
+
+All are actively used - no dead code found.
+
+---
+
+## Conclusion
+
+**Current state:**
+- Backend, runner, pocketbase, caddy: ✅ Already well-optimized
+- UI: ⚠️ Carrying 300MB of unused dependencies
+
+**Impact of cleanup:**
+- 73% smaller UI image
+- Faster deployments
+- Lower bandwidth costs
+- Cleaner dependency tree
+
+**Effort:** ~5 minutes (remove 2 packages + regenerate lockfile)
+**Risk:** Very low (confirmed unused via code search)
