Implements an e-ink daily dashboard plugin ("today") with four sections:
date/focus/success header, agenda timeline, chores checklist, and
due/overdue task lists.
Data sources:
- Focus & success text: Tana daily note (src/sources/tana.ts)
- Due/overdue tasks: Tana task search (src/sources/tana.ts)
- Agenda events: ICS calendar feeds (src/sources/ics.ts)
- Chores: Donetick API (src/sources/donetick.ts)
All sources fetch in parallel and fall back gracefully on error.
Tests use mock HTTP servers with synthetic data — no real services needed.
