fix(notification): add role=link and touch target to view-all button

- role="link" restores screen reader link semantics (Leonie blocker)
- min-h-[44px] px-1 meets WCAG 2.2 §2.5.8 and our 44×48px target size
- Comment in handleViewAll explains close-before-navigate ordering
- Tests updated to getByRole('link') + new call-order assertion

 These modules are resolved at static import time (before any test runs). Their `vi.mock` factories are served by birpc synchronously during module graph resolution, not after worker teardown.
 
+**Pattern note:** When an overlay or dropdown triggers a navigation action, use `<button type="button">` with an `onclick` handler that calls `goto(path)` — do **not** use `<a href="…">` with `e.preventDefault()`. SvelteKit registers its link interceptor as a capture-phase `document` listener, so it fires before the component's bubble-phase `onclick`. By the time `e.preventDefault()` runs the router has already initiated navigation, which tears down the vitest-browser Playwright orchestrator iframe. A `<button>` carries no `href`, so the capture-phase interceptor never fires. See `NotificationDropdown.svelte` for the canonical example.

 - New browser-mode specs that need to stub an external library **must not** use `vi.mock(externalLib, factory)`. Add a loader/factory parameter to the underlying hook or service instead.
 - The CI `unit-tests` job includes a permanent grep guard that fails the build if `rpc is closed` appears in any coverage run log. This catches regressions before they reach the acceptance criterion.
 - Acceptance criterion for #535: 60 consecutive green `workflow_dispatch` CI runs against `main` after the fix is merged, with zero `rpc is closed` lines in any log.
-- **Enforcement:** No automated lint rule is planned; the CI coverage guard is the regression backstop. If a lint rule is added later (e.g. an ESLint rule flagging `vi.mock` of non-virtual modules in browser-mode spec files), update this ADR.
+- **Enforcement:** An ESLint `no-restricted-syntax` rule in `eslint.config.js` (scoped to `**/*.spec.ts` and `**/*.test.ts`) flags any `vi.mock('pdfjs-dist', ...)` call with a message referencing this ADR. This turns a ~2-minute CI wait into an immediate lint error on save. The CI birpc grep guard remains as belt-and-suspenders for the coverage run. A CI static grep step (added in issue #546) also catches the pattern before the test suite launches.
 - **When to revisit the LibLoader home:** If three or more components adopt this pattern, consider extracting a shared `$lib/types/lib-loader.ts` or a generic `DynamicImportLoader<T>` type to avoid parallel type definitions across modules.
