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
