Instrumentation (all BT_AUDIO_LOG/BT_AUDIO_SPATIAL-gated): mech watcher-poll
probe (delayed flag + socket count via new Simulation::DebugAudioWatcherCount),
per-sim audio-socket size in ExecuteWatchers, trigger notifications (val>0),
watcher poll-rate/change probes, footstep pulse address trace.
VERIFIED working: FootStep binds to the real member (pulse addr == bound ptr,
same run); pulses fire per stride (40/run); the watcher registers on the mech
(audioWatchers=20 after audio-object creation); the mech's poll runs
(delayed=0, simFlags=0x1110); Logical == int (STYLE.H:132) matches the member
type. The idle<->moving engine crossfade (AudioMotionScale on LocalVelocity
through the restored watcher poll) is CONFIRMED audible in play.
REMAINING: the FootFall transient still doesn't reach SetupPatch -- next probe
is the trigger's streamed threshold/inverse config and the speed-scaled
transient volume at the renderer drop gate (LowAudioVolumeThreshold=0.3).
