fix(desktop): feed loading issues — missing events, broken profile navigation

- Profile feed now includes reposts (kind 6/16), not just text notes
- Metadata consume returns false to avoid wasteful null note lookups
- Feed subscription limits raised from 50 to 200 for global/following
- Thread replies subscription fetches NIP-22 comments (kind 1111)
- Cache now handles CommentEvent for thread display
- Wire onNavigateToThread through UserProfileScreen so tapping notes opens threads
