- Add USE_SDL CMake option (Auto/SDL2/SDL3) — prefers SDL3 when available
- All source files use #ifdef USE_SDL3 guards for API differences: Event types, key struct members, modifier keys, timer/window functions, ImGui backend (sdl2/sdl3), GLSL version (150/300 es), audio capture API, OpenGL proc loader, drop file handling
- Conditional SDL linkage: SDL3::SDL3 vs SDL2::SDL2 + SDL2::SDL2main
- New cmake/SDL3Target.cmake for SDL3 target verification
- Updated ImGui.cmake for conditional backend and kept ImGuiDemo target
- Updated dependencies_check.cmake and packaging-linux.cmake for SDL version
- Added audio device hotplug support for SDL3
- Added CurrentAudioLevel() and RefreshDeviceList() to AudioCapture
- Refactored drop file handler into HandleDropFile() method
- SDL3 audio capture uses SDL_AudioStream API
- SDL key constants remapped via #undef/#define for SDL3 naming
- Guarded projectm_create_with_opengl_load_proc for older libprojectM
- CI builds both SDL2 and SDL3 on all four platforms: Ubuntu Linux, Arch Linux, Windows (vcpkg), macOS (Homebrew)
- vcpkg.json includes both sdl2 and sdl3
- Windows runner pinned to windows-2022 for VS 2022 compatibility
