* Upgrade the frontend from SDL2 to SDL3
Port the ewm crate from the sdl2 crate (0.38) to sdl3 (0.18.4),
linking against Homebrew SDL3 via pkg-config. Behavior is unchanged.
- sdl.rs: SDL3 removed SDL_RendererInfo, so the texture-format probe
walks the renderer properties instead; the accelerated check becomes
a software-renderer name check (the ACCELERATED flag is gone), and
RGB888 is now spelled XRGB8888.
- snd.rs: the SDL2 AudioQueue becomes an SDL3 audio stream. The
queued_bytes() backpressure cap replaces AudioQueue::size(), and the
prime-then-resume order keeps the underrun headroom (SDL3 devices
start paused). SDL3 has no per-device sample-buffer request.
- boo.rs/one.rs/two.rs: into_canvas() is infallible with no builder,
set_logical_size() takes a presentation mode, the timer subsystem is
replaced by sdl3::timer::ticks(), text input is per-window,
fullscreen is a bool, Keycode::Num1 is Keycode::_1, and the game
controller subsystem is now gamepads with positional button names
(A/B/X/Y -> South/East/West/North).

* Phase 9: remove the C tree, promote the Rust workspace to the root
Pure git mv / git rm plus the mechanical path fixes:
- Delete src/*.c, src/*.h, src/Makefile, src/CMakeLists.txt, the Lua
scripts, .travis.yml, and scripts/gen-golden-trace.* (the golden
trace regeneration needed the C tree; the checked-in golden file is
now frozen — regenerating requires the C from git history).
- git mv src/rom -> rom and rust/* -> the repo root.
- Fix include_bytes! and test paths for the new layout (src/rom ->
rom, one directory level less). No other code changes.
