release: v3.0.0 — navigation overhaul, Work view, and multi-pin supportv3.0.0

Reworks the app's core navigation and home screen for v3.0.0:

- Replace Inbox with Work view: unified dashboard showing unread threads
  and assigned tickets, with All/Unread/Assigned scope picker
- Overhaul Home screen: redesigned with pinned items grid (trackers,
  repos, mailing lists, users), recent activity section, and system
  status banner; backed by HomePinStore supporting all resource types
- Simplify navigation bars across list screens: default toolbar shows
  only the primary action (+) and an overflow menu (…); pin, share, and
  select moved into the overflow menu; selection mode gets its own nav
  bar with Cancel / "N Selected" / All
- Consolidate repo detail toolbars: pin and share moved into the
  existing actions menu for both Git and Mercurial detail views
- Add recent activity tracking via RecentActivityStore
- Add work and inbox deep link aliases (hutch://work, hutch://inbox)
