feat(app-registry): wire up 4 modules + 7 routes + tier-patch validator

Resolves the cross-cutting drift that the app-registry sanity-test was
silently catching but BRANDING_ONLY exceptions papered over.

App-registry wiring:
- Register augur, broadcasts, invoices, timeline as workbench cards.
- Resolve agents↔ai-agents naming drift: workbench id is now `agents`
  (matches MANA_APPS + the /agents route URL); folder stays `ai-agents`
  for grouping with other ai-* modules.

Broadcast→broadcasts unification:
- module.config appId, MANA_APPS id, APP_ICONS key, all route appIds,
  and the redundant APP_URL_OVERRIDES entry — all aligned with the
  earlier folder rename so nothing diverges anymore.

Top-level routes for workbench-only modules:
- /goals, /myday, /kontext, /rituals, /automations, /activity — thin
  RoutePage wrappers around the existing module ListViews.
- /timeline becomes a real module (ListView extracted from the route),
  route shrinks to a 12-line wrapper.

Food unarchive:
- packages/shared-branding/src/mana-apps.ts: remove `archived: true`
  from food entry. The module is fully wired (registered, synced,
  routed, with AI tools); the flag was outdated.

i18n cleanup:
- Rename ai-agents → agents key in all 5 apps locales.
- Drop dead "observatory" key from all 5 nav locales (route folder was
  removed in 7bca16dfa).

New CI guard — scripts/validate-tier-patches.mjs:
- Scans for `LOCAL TIER PATCH — revert before release` markers.
- Default: informational list (does not fail).
- Strict mode (MANA_TIER_PATCH_STRICT=1) for release/RC pipeline.
- Wired into validate:all.

Spec update:
- registry.spec.ts WORKBENCH_ONLY/BRANDING_ONLY: documented Settings
  family + AI Studio surfaces + intentionally-internal modules so the
  drift guard fires only on real drift.
