- Remove Music button, OnMusic/RunMusicAsync/StopMusic and all music fields
- MusicAnalyzer: remove Analyze, DecodeToMono, MusicPattern record;
keep ExtractFeatures/MapPitchToPeriod/BuildWaveFrame/TickFeature (used by LiveCapture)
- Remove unused NAudio.Wave and System.Diagnostics imports from MainForm
- Fix LiveCapture overlap: sliding window with 50% overlap (was dropping every other frame)
- Buttons resized to 80px (Test/Live/Pattern/Stop All)
- LiveCapture.cs: real-time WASAPI loopback capture with rolling buffer
and continuous FFT analysis, enqueues WaveFrames at ~10Hz
- MusicAnalyzer.cs: refactored ExtractFeatures/MapPitchToPeriod/BuildWaveFrame
as public reusable methods with sampleRate parameter
- MainForm: audio device selector (defaults to system default), Live button
starts/stops capture, Stop All stops live too
- Adaptive normalization (running max with slow decay) for live volume changes
