chore: Arc B580 offload spike script
...
Read-only probe: CUDA unusable, OpenCL sees the B580, OpenVINO not
installed. Per-worker GPU still out of scope.

Also extend bench_enhance.py with --stereo --hop for isolated RTF.

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).

Default TORCH_NUM_THREADS=1 so 14-20 workers do not each spawn a
28-thread BLAS pool.

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.
