Musify for Windows v10.1.2-port2

v10.1.2-port2 — Animated backgrounds + stability fixes 🪟

✨ New

• Animated canvas backgrounds — 7 patterns (synapse, rain, constellations, sparkles, embers, bubbles, squares) that change with the music
• Adaptive speed — slow (120s cycle) on pause, faster (60s cycle) while playing
• Segoe Fluent Icons — modern Windows 11 native icons (no custom fonts needed)

🐛 Fixed

• Playback on Windows — AndroidEqualizer and other Android-specific code now properly guarded behind Platform.isAndroid checks
• Background visibility — renders on top of content as semi-transparent particle overlay so it's always visible
• Click-through — background has IgnorePointer so it doesn't block UI interactions
• Color contrast — particles auto-brighten on dark themes so they're never invisible
• Stability — removed redundant AnimationController.repeat() calls that caused freezes on rapid song changes

🧹 Housekeeping

• Removed 'Predictive back (Android 14+)' option from Settings on Windows
• Updated README with portable focus
• Added Windows port info to About page
• GitHub repo description and topics updated
