Implement activity log (task 22)

- activity_log table in _core/schema.ts with household+created_at index;
  migration 0008_activity_log.sql applied
- logActivity() in _core/activity.ts reads current session and inserts a row
- ActivityLogEntry type + renderActivity?(entry): string added to
  EntityTypeRegistration so modules declare human-readable labels without
  any if/else branches in the widget
- core.activity widget replaced with a real async server component that
  queries the last 20 rows and renders via the registry
- logActivity wired into every create/update/delete in calendar, lists,
  and notes server actions; getAuthorizedItem also returns text so
  toggle/delete can include item text in the payload
- pnpm typecheck, lint, build, and all 4 E2E specs pass

 - **12 — Notes module**. Added generic core `reminders` table plus household-scoped `notes` schema in migration `0006_new_hannibal_king.sql`, notes CRUD server actions, reminder synchronization for `notes.note`, `/notes` index, `/notes/new`, `/notes/[id]` editor with safe markdown preview, manifest entity/search/reminder/share registration, `notes.filtered` widget registration, quick-add placeholder, and Playwright happy-path spec in `tests/e2e/notes.spec.ts`. `pnpm typecheck`, `pnpm lint`, `pnpm build`, and notes E2E pass.
 - **20 — Dashboard composition (single-dashboard MVP)**. Added `default_dashboard_layout` jsonb column to `users` + migration `0007_uneven_living_lightning.sql`. Created `src/modules/_core/manifest.tsx` (`core.activity` placeholder widget) and registered it. Updated all three module manifests (calendar, lists, notes) with real async server component widget renders (data-fetching, empty states). Created `src/lib/dashboard.ts` (layout parsing + `computeDefaultLayout` greedy packer). Built `src/app/page.tsx` — 12-col CSS Grid, static `smColSpan` lookup for Tailwind class safety, per-widget `<Suspense>` for parallel loading, graceful skip for unknown widget IDs. `pnpm typecheck`, `pnpm lint`, `pnpm build`, and all 4 E2E specs pass.
 - **21 — Quick-add registry**. Added `url: string` to `QuickAddAction` type (action is now optional). Added `getQuickAdds()` / `SerializedQuickAddItem` to registry (strips non-serializable `action` fn before crossing server→client boundary). Updated all three module manifests with navigation URLs. Built `QuickAddProvider` (context + cmd+k global shortcut), `QuickAddFab` (opens sheet, replaces plain button in dashboard), `QuickAddSheet` (bottom drawer / desktop popover grouped by module), and `CommandPalette` (cmdk-powered modal with arrow + enter + esc keyboard nav). Provider in root layout receives actions from `getQuickAdds()` at render time — adding a module's `quickAdds` automatically appears in both surfaces. Also added `.claude/**` to ESLint ignores to prevent stale worktree build artifacts from failing lint. `pnpm typecheck`, `pnpm lint`, `pnpm build`, and all 4 E2E specs pass.
+- **22 — Activity log**. Added `activity_log` table to `_core/schema.ts` with index on `(household_id, created_at desc)`. Migration `0008_activity_log.sql` applied. `logActivity()` server function in `_core/activity.ts` reads current session and inserts a row. Added `ActivityLogEntry` type and optional `renderActivity?(entry): string` to `EntityTypeRegistration` in `_core/module.ts`. All three module manifests implement `renderActivity` for each entity type (human-readable, no hardcoded branches in the widget). Replaced `core.activity` widget stub with a real async server component that queries the last 20 rows via `getEntityType(entry.entityType)?.renderActivity(entry)`. Wired `logActivity()` into every create/update/delete in calendar, lists, and notes server actions. Also added `text` to `getAuthorizedItem` select so toggle/delete log the item text. `pnpm typecheck`, `pnpm lint`, `pnpm build`, and all 4 E2E specs pass.
