syncduke: OPL3 MIDI music + digital-audio polish

Builds on the SFX path (5b29253803 diabetes-21-onto) with in-process music
and a round of audio fixes, all through termgfx's SyncTERM audio-APC manager:

- Music: render the GRP's MIDIs via libADLMIDI (OPL3), peak-normalized, cached
as OGG/Vorbis (libsndfile, build-gated TERMGFX_WITH_SNDFILE) under a content-
addressed m/<track>.ogg so a track uploads once; raw-WAV fallback otherwise. - SFX: transcode the VOCs libsndfile rejects (multi-block) to 8-bit WAV.
- Setup Sound volume sliders wired (FX + music master) and SOUND/MUSIC toggles. - Looping ambient (FX_PlayLooped*) on dedicated channels; stop on door exit.
- soundonce flood fix: a door-side per-sound rate limit. Returning a real voice
handle so the engine's Sound[].num gate works would deadlock newgame()'s
busy-wait on the skill-announce voice (the engine assumes an async audiolib
completion source our APC path lacks), so instead we drop a same-sound
re-dispatch inside an 8-tick window -- collapsing a per-tic soundonce stream
to one burst while leaving real weapon fire untouched.

New termgfx audio module (audio_midi.{c,h}) + audio.c/audio_mgr.c additions; syncduke wires them through its FX_/MUSIC_ stubs.
