feat(cache): wire State classes on DesktopIAccount for GC retention

- Add BookmarkListState, Kind3FollowListState, Nip65RelayListState
  to DesktopIAccount — pins important AddressableNotes via strong refs
- Create stub Kind3FollowListRepository + Nip65RelayListRepository
  (no persistence yet, null backups)
- Update followingKeySet() to read from Kind3FollowListState.flow
- Revert accidental long-form branch changes in DeckColumnContainer
