port(audio): D202 M-67-M-69 runtime probes — GE_VOICEDUMP, [VOICEMAP], timestamped [WIRE]/[EVT]/[STOP-EVT]

Browse Source 
Env-gated diagnostics for the D202 per-voice sample-correctness work
(M-67/M-68/M-69), all inert unless the env var is set:

- GE_VOICEDUMP (mixer.c aEnvMixerImpl): per-voice resampled mono stream
  to voicedump.raw, records [stateAddr][nSamples][us][s16 x n]. NB the
  us stamp is mix time — records render ahead, samples END at the stamp.
- [VOICEMAP] (synthesizer.c, under GE_AUDIOTRACE): full PVoice ->
  decoder/resampler/env-state address map at synth init, tying voicedump
  slot addresses to WIRE filter addresses.
- [WIRE] (load.c) now carries a µs timestamp; sndPlaySfx trace gains
  t=µs + wavetable pointer.
- [EVT]/[STOP-EVT] (snd.c): every ALSndpEvent the player processes, plus
  the release ramp a STOP/DEACTIVATE computes (deltaUs).
- audiodebug.ps1: -VoiceDump switch.

With scratchpad/exact_match.py these prove every allocated voice plays
the exact ROM sample at the exact ROM pitch (286/320 CC >= 0.85 on the
M-69 full-corpus run; remaining failures are dropped allocations + wire
attribution, not corruption). Remove once D202 closes.
