v0.9.5 beta — full feature build ready for distribution

Core additions since initial commit: - Platform-split MIDI (midi_linux.c / midi_windows.c) - Patch system: save/load/scan, subdirectory navigation, favourites - Config system: last MIDI device and CC mappings persisted to disk - Custom embedded pixel font and sprite sheet (no loose asset files at runtime) - Window icon embedded at runtime (SetWindowIcon) and in Windows .exe (windres) - chdirToExeDir() in platform.c so double-click launch finds patches/ correctly - About screen accessible from Master panel UI polish: - TITLE_BAR_H constant (20 px) — sprite buttons now fit inside title bars - All title bar text, button overlay text, and close/active labels vertically centred - Full-screen dim overlay computed from camera transform (no more partial coverage) - Patch browser: folder navigation, breadcrumb title, 256-slot limit lifted Build: - Makefile auto-discovers sources; embeds sprites/font/icon via xxd rules - Windows cross-compile: make PLATFORM=windows (mingw-w64 + windres) - windows.h isolated in platform.c to avoid Rectangle/CloseWindow conflicts with raylib.h - WIN_RES uses lazy = assignment so OBJ_DIR expands correctly for windres output path Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
