Log Message:
doors: SyncDOOM terminal music + cross-session audio caching (both doors)

Wires music into SyncDOOM and adds a shared, cross-session OGG cache to
termgfx so both doors stop re-rendering and re-uploading the same tracks.

SyncDOOM music (new):
- i_termmusic.c: a Doom music_module_t that renders each level's MUS/MIDI
lump to OPL3 PCM (termgfx_midi_render/libADLMIDI -- adl_openData auto-
detects MUS, no mus2mid) and loops it over SyncTERM's audio APC. Wired in
i_sound.c's InitMusicModule(); title-song tier-deferral + stop-on-exit.
- m_menu.c: restore a "Sound Volume" item (replacing the moot-in-a-terminal
Graphic Detail toggle) so the existing Music Volume slider is reachable.

termgfx audio caching (shared -> both doors):
- Full-song loops: render cap 120s -> 600s (Doom tracks run to ~374s; the
old cap looped them mid-song).
- Door-side OGG disk cache: encode once, write to <data>/<door>/audio (the
SCFG data_dir via $SBBSDATA, else beside the WADs/GRP), ship from disk
after -- render happens once globally.
- C;L client-cache skip: at tier-ready query SyncTERM's persistent cache and,
on a name hit, Load straight from it -- no render AND no upload. Mirrors
the zmachine's C;L pattern; name-presence (content-addressed), not MD5.
- Cache names are consumer-namespaced + descriptive: <door>/music/<hash>_v<n>
and <door>/sfx/<num> -- distinct + attributable in SyncTERM's one per-BBS
cache dir (vs the terse, collision-prone shared m/ a/). Both doors content-
hash music so a shared dir never serves the wrong track. Render-version tag
invalidates cleanly if the synth changes.

Input fix (both doors): the parsers now swallow APC/DCS/OSC/PM string
sequences (ESC _ ... ESC \). The new C;L reply is an APC literally containing "C;L", and the old parsers leaked it as keystrokes -- the 'l' hit Load Game.

Music-vs-SFX balance capped low (OPL music is sustained + peak-normalised). Each play logs which path it took (client-cached / disk-cached / rendered).
