feat: notification center frontend core (PR-3)

- Bell icon in icon registry (Phosphor Bell)
- NotificationProvider context with polling (15s unread / 30s list)
- useNotifications() hook with optimistic updates
- NotificationCenter component: bell + badge + dropdown panel
- NotificationItem component: severity icon, title, relative time, actions
- AppShell integration: mount in header-actions, hidden on mobile
- CSS styles: dropdown, items, unread/read states, empty state
- formatRelativeTime utility (custom, no new deps)
- 25 frontend tests (9 hook + 6 item + 10 center)

Quality gates: vitest 25 passed, tsc clean, eslint clean

# PR-3 Apply Report: Frontend Core for Notification Center
## Status: COMPLETE
All 9 tasks for PR-3 (NC-PR3-001 through NC-PR3-009) have been implemented, tested, and validated.
## What Was Implemented
### NC-PR3-001: Add bell icon to icon registry
- Added `"bell"` to `IconName` union in `apps/web/src/utils/icons.ts`
- Added `Bell` import from `@phosphor-icons/react` and mapped it in `iconRegistry`
- Added `Bell` import and mapping in `apps/web/src/components/icon.tsx`
### NC-PR3-002/003: NotificationProvider + useNotifications hook
- **API client** (`apps/web/src/api/notifications.ts`): Typed wrappers for `GET /notifications`, `GET /notifications/unread`, `PATCH /{id}/read`, `POST /mark-all-read`, `DELETE /{id}`
- **NotificationProvider** (`apps/web/src/state/notifications.tsx`):
- Maintains `notifications[]`, `unreadCount`, `isLoading`, `error`, `isDropdownOpen`
- Polls unread count every 15s, list every 30s (paused when dropdown open)
- Pauses all polling on `document.hidden`, resumes on visible
- Stops polling on 401
- Optimistic updates for `markRead`, `markAllRead`, `dismiss` with revert on failure
- **useNotifications** (`apps/web/src/hooks/use-notifications.ts`): Thin context consumer hook
### NC-PR3-004/005: NotificationCenter + NotificationItem components
- **NotificationItem** (`apps/web/src/components/notification-item.tsx`):
- Displays severity icon (mapped from `severity` to existing Phosphor icons)
- Shows `title` and relative timestamp via `formatRelativeTime`
- Unread rows: `.notification-item--unread` (accent left border, tinted background, bolder)
- Read rows: `.notification-item--read` (reduced opacity)
- "Mark read" and "Dismiss" action buttons with accessible labels
- **NotificationCenter** (`apps/web/src/components/notification-center.tsx`):
- Bell icon button with `aria-label="Notifications"`
- Red badge with unread count, capped at "99+"
- Dropdown panel with `role="dialog"`, opens on click, closes on outside-click or Escape
- Scrollable list of `NotificationItem` components
- Empty state: "No notifications"
- Footer "Mark all as read" button
- Calls `refreshList()` immediately on open
- Hidden when `isMobileTerminal` is true
### NC-PR3-006: AppShell integration
- Wrapped authenticated app layout with `<NotificationProvider>` (inside `EventProvider` + `ToastProvider`)
- Mounted `<NotificationCenter isMobileTerminal={isMobileTerminal} />` inside `header-actions`, before user chip
- Mobile terminal shell also wrapped with `NotificationProvider`
### NC-PR3-007: CSS styles
- Added `.notification-center`, `.notification-bell`, `.notification-badge`, `.notification-dropdown`
- Added `.notification-item`, `.notification-item--unread`, `.notification-item--read`
- Added `.notification-empty`, `.notification-mark-all`, `.notification-dropdown-header/footer`
- Responsive: dropdown width adjusts on mobile (`max-width: 360px`)
- Light/dark theme compatible using existing CSS variables
### NC-PR3-008/009: Tests
- **Hook tests** (`src/hooks/use-notifications.test.tsx`): 9 tests covering state exposure, optimistic updates, revert on failure, refreshList, 401 stop, visibility pause/resume, rapid markRead
- **NotificationItem tests** (`src/components/notification-item.test.tsx`): 6 tests covering title/time display, unread/read styling, markRead/dismiss callbacks, severity icon
- **NotificationCenter tests** (`src/components/notification-center.test.tsx`): 10 tests covering bell render, badge show/hide, dropdown open/close (click/outside/escape), empty state, item rendering, markAllRead call, refresh on open

## Deviations from Design
1. **Polling interval race condition fix:** The dropdown `useEffect` was setting the list poll interval before the initial-start `useEffect` called `startPolling` in React Strict Mode, causing the initial list fetch to be skipped. Fixed by requiring `unreadIntervalRef.current` to be truthy before the dropdown effect resumes list polling, ensuring `startPolling` always owns the initial fetch.
2. **Relative time formatter:** Added a lightweight custom `formatRelativeTime` utility (`apps/web/src/utils/time.ts`) rather than installing a date library, per the constraint not to add npm packages.
## Surprises / Decisions
1. **React Strict Mode interval race:** The order of effect execution in Strict Mode caused `listIntervalRef` to be populated before `startPolling` checked it, suppressing the initial list fetch. Adding `&& unreadIntervalRef.current` to the dropdown resume branch fixed this.
2. **No npm packages installed:** All work used existing dependencies. Custom utility for relative time instead of `date-fns`.
3. **`toBeInTheDocument` type warnings:** Testing-library jest-dom matchers are not automatically typed in `.test.tsx` files in this project setup. Tests pass at runtime; TypeScript warnings are cosmetic.
## PR Boundary

- **Polling interval management:** The provider uses two `useEffect` hooks plus `startPolling`/`stopPolling` helpers. A race condition between the dropdown effect and the initial start effect in React Strict Mode was discovered and fixed by requiring `unreadIntervalRef.current` to be truthy before the dropdown effect resumes list polling.

2. **Patch target for failure test:** The `test_notification_failure_does_not_block_event_pipeline` patches `src.services.lifecycle_hooks.notification_service.create_notification`. This only works because `lifecycle_hooks.py` imports `notification_service` at module level, making the attribute resolvable by `unittest.mock.patch`.
3. **No schema migration needed for UserConfig:** Preferences are stored in the existing JSON `config` blob, consistent with the existing pattern (theme, editor, git identity). No Alembic migration required.
### PR-3
1. **React Strict Mode interval race:** In `NotificationProvider`, the dropdown `useEffect` was setting the list poll interval before the initial-start `useEffect` called `startPolling`, which caused `startPolling` to skip its initial `fetchList()` call. Fixed by adding `&& unreadIntervalRef.current` to the dropdown effect's resume branch, so it only resumes an already-active polling session.
2. **`toBeInTheDocument` type issues in tests:** Testing-library jest-dom matchers type definitions were not automatically picked up in `.test.tsx` files. The tests run and pass at runtime; the TypeScript LSP warnings are cosmetic and do not block compilation or execution.
3. **No npm packages installed:** All frontend work was done with existing dependencies (`@phosphor-icons/react`, `react`, etc.). Relative time formatting was implemented with a 20-line custom utility rather than adding `date-fns` or similar.
