root b02138669a perf: reuse GCC-PHAT TDOA; skip 16 kHz AudioNormalizer 
Delay-and-Sum still uses the tutorial STFT/cov/GCC-PHAT/DelaySum/ISTFT
path. TDOA is refreshed every BEAMFORM_TDOA_EVERY hops (default 5).

root 23c2e9c4c0 perf: cap torch threads per camera worker 
Default TORCH_NUM_THREADS=1 so 14-20 workers do not each spawn a
28-thread BLAS pool.

root 950128deec feat: DelaySum beamform plus hop process latency 
Keep C920 stereo through SpeechBrain GCC-PHAT Delay-and-Sum, then
MetricGAN, and publish mono to LiveKit. Record last_dt_ms and log
process_ms/capture_ms every 50 hops for the latency plan.
