v0.9.0 - Performance & UI Improvements

- Custom Canvas 2D chart renderer replaces Chart.js for 30fps streaming performance
- Language color indicators in table rows for visual correlation with chart

- Improved keyboard shortcut hints (space to play, S to toggle sound)
- High-DPI display support with devicePixelRatio handling
- Data decimation for smooth chart rendering with large datasets (6000+ commits)

- Fixed 4x mode drum pattern: kick on beat 1, snare on beat 3 (half-time feel)
- Chord changes remain on main downbeat of 1

- 100% of frames under 16ms (60fps capable)
- Zero slow frames (>33ms) during 6120 commit playback at 4x speed
- Average frame time: 3.79ms

v0.8.1: Fix audio pulsing/bursting during playback

v0.8.0 - Sparse audio data format optimization

v0.7.0: Multi-octave audio frequency system

- Redesigned audio frequency allocation across 2+ octaves (C3 to B4)
- Eliminated 'thrumming' with random phase detuning (±3 cents)
- Fixed muddy bass tone - dominant languages now have distinct harmonic voices
- Timbral changes now audible as codebase language mix evolves
- Fixed audio initialization fade-in to prevent clicks/pops

Addresses user feedback on Express.js repo (6K+ commits) where JavaScript
dominated sound was muddy with no timbral variation.

Update to v0.6.0

v0.5.1: Remove audio debug logs, increase volume variation
