Implement quick-add registry (task 21)

- Add url field to QuickAddAction; make action optional
- Add getQuickAdds() + SerializedQuickAddItem to registry so quick-add
  data can cross the server→client RSC boundary without serializing fns
- Update calendar/lists/notes manifests with navigation URLs
- QuickAddProvider wraps root layout: holds sheet/palette open state and
  global cmd/ctrl+k shortcut
- QuickAddSheet: bottom drawer on mobile, right-side popover on desktop,
  actions grouped by module
- CommandPalette: cmdk-powered modal with fuzzy filter and full keyboard
  nav (arrows + enter + esc)
- QuickAddFab: client button replacing the plain + stub in the dashboard
- Add .claude/** to ESLint ignores to prevent stale worktree artifacts
  from failing lint

All 4 E2E specs pass; typecheck, lint, and build clean.

 - **11 — Lists module**. Added `lists` and `list_items` schema + migration `0004_opposite_wraith.sql`, default Shopping/Tasks seeding on first access/sign-in/seed, household-gated list and item CRUD server actions, reorder support, and Postgres `LISTEN/NOTIFY` to SSE bridge documented in ADR `0002`. Added `/lists` grouped index, `/lists/[id]` keyboard-first item entry with checkbox toggles and swipe/delete, manifest entity/search/widget/quick-add registrations, and Playwright happy-path spec in `tests/e2e/lists.spec.ts`. `pnpm typecheck`, `pnpm lint`, and `pnpm build` 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.

+## Implementation notes
+
+- `QuickAddAction` gained a `url: string` field; `action` made optional (future inline modals).
+- `SerializedQuickAddItem` strips the non-serializable `action` fn so it can cross the server→client RSC boundary as props to `QuickAddProvider`.
+- `getQuickAdds()` in the registry returns one `SerializedQuickAddItem` per registered quick-add, enriched with `moduleId` / `moduleName` for grouping.
+- Root layout calls `getQuickAdds()` and passes the result to `<QuickAddProvider>` which wraps the whole app. `<QuickAddSheet>` and `<CommandPalette>` live inside the provider and read from context.
+- `cmdk` installed for the command palette; keyboard shortcut (cmd/ctrl+k) wired via `useEffect` in the provider.
+- `.claude/**` added to ESLint ignores to prevent stale worktree `.next` build artifacts from failing lint.
