Implemented musical note detection in AudioAnalyzer, exposing dominant note and strength in AudioFeatures. Updated HUD to display detected note. Added "NOTEDROP" fractal preset that animates detected notes as colored glyphs. Extended bitmap font to support sharps. Increased fractal preset count and adjusted HUD layout.
