WIP: port deferred input/audio stubs to real SDL 3 APIs
Phase 7-8 of the migration. Replaces the per-subsystem stubs added in the earlier "builds clean" commit with proper SDL 3 implementations. - gfxengine: add SDL_Window* accessor window_handle() so callers that need to talk to SDL 3's window APIs (grab, text input) can reach it. - states.cpp mouse grab: SDL_WM_GrabInput → SDL_SetWindowMouseGrab. Drops the local SDL_GRAB_* / SDL_WM_GrabInput stub macros. - states.cpp text input: SDL_EnableUNICODE → SDL_StartTextInput / SDL_StopTextInput. kobo.cpp event loop now handles SDL_EVENT_TEXT_INPUT (in both quit_requested() and the main game loop) and forwards each byte of the UTF-8 string as a unicode value to gsm.press(-1, ch) so the high-score name-entry path keeps working without any state-side changes. - kobo.cpp joystick: full re-port of init_js / close_js using SDL_GetJoysticks (returns SDL_JoystickID array), SDL_OpenJoystick, SDL_CloseJoystick. options.cpp joystick enumeration already used the new API from the previous commit. - sound/audio.c: replace the silent stub with a real SDL 3 backend built on SDL_OpenAudioDeviceStream + an SDL_AudioStreamCallback. The engine's existing _audio_callback (Sint16 stereo fill-buffer) is kept; a small adapter (sdl3_stream_callback) runs it on a scratch buffer and pushes the result via SDL_PutAudioStreamData. audio_lock/unlock now call SDL_LockAudioStream / SDL_UnlockAudioStream. After this commit the binary opens an audio device successfully and the joystick path resolves real SDL 3 calls. Renderer + audio + input are now all on SDL 3 with no compat shims. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
