## Summary
- stop retrying remote read-state publishes after the local replacement
blob exceeds NIP-44's 65,535-byte plaintext limit
- preserve every local read marker and leave existing relay state
untouched rather than truncating remote state
- keep incoming remote read-state available while suppressing further
invalid publishes for the manager lifetime
## Why
A repaired/reconnecting relay exposed a 1,404-context read-state on iOS.
The app repeatedly serialized and attempted to encrypt that structurally
oversized blob while reconnect catch-up work was running, saturating
Flutter's debug UI isolate and making channel navigation take roughly
ten seconds.
This is intentionally fail-closed and behavior-preserving: local read
behavior continues, but remote publishing pauses until the manager is
recreated. No protocol or persisted-data format changes.
## Verification
- `flutter test` — 1,093 passed, 1 skipped
- `flutter analyze` — no issues
- pre-push `mobile-test` and `branch-skew` hooks passed at
`0b6423c5d4d583194f0bbe69662912133b9ae1ef`
- independent review by Princess Donut: no blocking findings;
compatibility-safe and correctly fail-closed

## Summary
- make mobile unread state visible with bold channel names, an animated
Inbox badge, and swipe-to-toggle Inbox rows
- add directional transitions for top-level mobile navigation
- let mobile send while media uploads, with cancellable progress UI
- normalize iOS and Android video uploads, attach poster frames, and
improve native video playback
## Validation
- `just mobile-check`
- `just mobile-test`
- `cargo test -p buzz-media`
- Pixel smoke test
- iPhone smoke test
Desktop background uploads moved to #4522 so the two platforms can be
reviewed independently.
