Recording:
- stopRecording() now only sets stopRequested=true, no longer cancels task
- Task exits polling loop naturally → merges TS segments → exports MP4
- System share sheet + Photos save shown on completion
- Added HEAD request to detect HLS Content-Type for non-.m3u8 URLs
- Faster exit when stopRequested && segments exist
Playback:
- Copy imported files to app Documents sandbox (security-scoped URLs expire after defer)
- Remove Referer header that blocks some streams; use iPhone UA only
- AVURLAsset options only for http/https schemes
Media Library UI (iOS):
- Replace NavigationSplitView with VStack + horizontal category chips
- Search bar at top, swipe actions for queue/delete
- scrollDismissesKeyboard(.interactively) on list
- Tap gesture sends resignFirstResponder to dismiss keyboard
- Compact rows with context menu, inline play button
- Close button in navigation bar
- presentationDetents(.medium) for tag/playlist sheets
