feat(ui): adaptive 3-panel layout, chat panel switching, audio metering fix
- Add responsive breakpoints (compact <600, medium 600-1023, expanded >=1024)
- Add ViewportInfo InheritedWidget for layout-aware descendants
- Add inline ChatPanel (380dp right column) for expanded desktop layout
- Add channel right-click context menu with Chat option for in-place switching
- Add per-target draft persistence via restoredDraft/onDraftChanged callbacks
- Fix header chat button to switch to current voice channel when panel open
- Fix close = dismiss (preserves last target and draft for reopen)
- Add unread dot indicator on channel tiles when chat is closed
- Fix audio regression: decimate dBFS computation to every 3rd callback (~31 Hz)
to avoid buffer underruns on macOS CoreAudio real-time thread
- Add tools/build-macos.sh release build script (7-step process)
- Add chat panel switching implementation plan and 3-panel design spec
