- Add user_sessions PocketBase collection (user_id, session_id, user_agent, ip, created/last_seen)
- Extend auth token format to include a per-login authSessionId (4th segment)
- Hook validates authSessionId against DB on each request; revoked sessions are cleared immediately
- Login/register create a session record capturing user-agent and IP
- Profile page shows all active sessions with current session highlighted; per-session End/Sign out buttons
- GET /api/sessions and DELETE /api/sessions/[id] endpoints for client-side revocation
- Backward compatible: legacy 3-segment tokens pass through without DB check
- Add `users` PocketBase collection (username, password_hash, role, created)
- Implement HMAC-SHA256 signed cookie auth in hooks.server.ts; token payload is userId:username:role
- Add User type, getUserByUsername, createUser (scrypt), loginUser (timing-safe) to pocketbase.ts
- Add login/register page with tabbed form UI and server actions
- Add logout route that clears the auth cookie
- Add layout.server.ts auth guard: redirect unauthenticated users to /login
- Extend App.Locals and App.PageData with role field
- Add AUTH_SECRET, POCKETBASE_ADMIN_EMAIL/PASSWORD to .env.example
- Install @types/node for Node crypto/scrypt types
