pre-ship: resolve the new audio diagnostic gates ONCE instead of per frame

Browse Source 
RunSequence and AudioIdleWatcher::Execute run per sequence per frame, so the
BT_ATTRBIND_LOG probes added while chasing #99 were calling getenv ~2700x/sec on
a 15-sequence mech.  Small, but this is the same path the source-pooling fix
(#32) just bought 10% of frame time in, and an unset diagnostic should cost
nothing.  Cached in function-static flags.

Pre-ship smoke (combat, 2 kills, a respawn, clean teardown):
  frame time 7.18 / 8.27 / 8.71 ms  -- matches the post-pooling 7.79ms baseline
  0 asserts, 0 access violations, 0 audio acquireFails
