feat: add bounded agenda view

Browse Source 
Add a read-only 42-day occurrence agenda with keyboard navigation, six-week paging, exact return-to-grid focus, search and calendar overlays, and bounded recurrence expansion.

Keep agenda state outside persistence, document month-only mutations, and cover empty windows, filtering, overlays, navigation, rendering, and terminal restoration.
