Claude 92cc09e908 feat(02-03): add librosa beat detection module (lightsync/audio/beats.py) ...

- analyze(path) -> {tempo: float, beats: [float, ...]} using librosa.beat.beat_track
- Returns beat timestamps in seconds converted from librosa frame indices
- analyze_async() wraps in asyncio.to_thread for non-blocking use from FastAPI
- Supports MP3/WAV/FLAC/OGG via librosa's ffmpeg/soundfile fallback chain
