feat(ui): implement state manager pattern, eliminate 3 sync flags
Phase 1 Progress - Convert UI Cleanup (dev23): Architecture Improvements: - Add SetSelectedSilent() method to ColoredSelect to prevent callback loops - Create convertUIState manager with setQuality(), setResolution(), setAspect(), setBitratePreset() - Eliminate syncingQuality flag (quality widgets use state manager) - Eliminate syncingAspect flag and syncAspect() function (aspect widgets use state manager) - Eliminate syncingBitratePreset flag (bitrate preset widgets use state manager) Impact: - Sync flags reduced from 5 to 2 (60% reduction) - Automatic widget synchronization (no manual SetSelected calls) - Single source of truth for UI state - Foundation for eliminating remaining sync flags Remaining: syncingBitrate, syncingTargetSize (text entry debouncing needed) Files modified: - internal/ui/components.go (SetSelectedSilent method) - main.go (state manager, widget callbacks)
