feat: personal/work area toggle

Global lens in the home header: every list, Today, Projects and Review
show only the active area; new rows are born into it. Tasks and projects
gain an area column (personal default); the task form's Area chip
re-files across areas.

 ## Layout
 
-- `app/` — Expo app (expo-router, TypeScript). Home shows the top 3 next actions plus a launcher menu: Today / Next / Waiting / Someday / Projects / Review.

+- `app/` — Expo app (expo-router, TypeScript). Home shows the top 3 next actions plus a launcher menu: Today / Next / Waiting / Someday / Projects / Review.
+  - **Personal / Work**: the toggle in the home header is a global lens — every list, Today, Projects and Review show only the active area, and new tasks/projects are born into it. Tasks and projects carry an `area` column (`personal` default); the task form's Area chip re-files a task across areas. The choice persists locally (`area_v1`). There is no inbox — every task is born fully scoped (title, priority, due date). Tap a task to clarify (list, project, context, waiting-for, due/defer dates, repeat).
   - **Quick add**: the title field parses tokens live — `Pay rent tmr p1 @home #Sydney ~30m monthly` — and mirrors them into the form.
   - **Repeat**: daily / weekdays / weekly / monthly / yearly; completing spawns the next occurrence (lapsed tasks catch up to today).
   - **Defer**: deferred tasks are hidden from action lists until their date; a footer link reveals them.
