Add real-time chord detection and visualization mode

Implemented chroma-based major/minor chord detection in AudioAnalyzer and exposed results in AudioFeatures. Updated HUD to display detected chord names. Added a new "CHORDS" fractal preset that visualizes the current chord with large pixel text, modulated by confidence and beat. Extended pixel font for chord display. Ensured graceful handling when no chord is detected. These changes enhance both analysis and visual feedback for harmonic content.
