ManuNotes for iOS 0.2.0

Simulator-only build. This does not install on a physical iPhone — that needs a paid Apple Developer Program enrollment (ad-hoc export or TestFlight), not yet active for this project. Unzip and drag ManuNotes.app onto a running iOS Simulator window, or xcrun simctl install <device> ManuNotes.app.

Added

• Redesigned notes list. A custom header (weekday, active-note count,
  search) replaces the system navigation bar, with filter chips for
  All/Favorites/Pinned/Archived and a floating bottom menu
  (Notes/Favorites/New/Archived/Search) that the list scrolls behind.
• Two card layouts. .stacked (new default) shows notes as full-width
  overlapping post-its with a colored border per note so same-color notes
  stay distinct when stacked; .classic keeps today's pastel grid. A
  toggle in the header switches between them and remembers the choice.
• Update checker. Compares the running build against the latest
  ios-v* tagged release on GitHub (this app's actual distribution
  channel until it's on the App Store) and shows a dismissible banner
  when a newer one exists, plus a manual "Check for Updates" entry and
  the current version/build number in the export/import menu.
• The current version now appears below the wordmark on the launch splash.

Fixed

• The update checker was comparing against the shared ManuNotes-releases
  repo's /releases/latest, which also hosts macOS's releases (tagged
  vX.Y.Z, no ios- prefix) — it now only considers ios-v* tags.
