docs: Add variable tempo architecture analysis
Comprehensive analysis of BPM dependencies and variable tempo requirements.
Key findings:
- BPM is baked into spectrogram generation (cannot change dynamically)
- Music time currently tied 1:1 to physical time
- Synth playback rate is fixed (no variable speed support)
Proposes solution:
- Global tempo_scale multiplier
- Unified music_time abstraction
- Variable synth playback with spectral interpolation
- Trade-off: pitch shifts with tempo (acceptable for demos)
Implementation roadmap: ~12 hours estimated effort
