ruv da54d21a38 fix(firmware): stack overflow risk + tick-rate independence (review findings) ... Critical fixes from deep review: 1. **Stack overflow prevention**: Moved BPM scratch buffers (br_buf, hr_buf) from stack to static storage in both process_frame() and update_multi_person_vitals(). Combined stack was ~6.5-7.5 KB of 8 KB limit — now reduced by ~4 KB to safe margins. 2. **Tick-rate independence**: Post-batch yield now uses pdMS_TO_TICKS(20) with min-1 guard instead of raw vTaskDelay(2). Previously assumed 100Hz tick rate. 3. **EDGE_BATCH_LIMIT to header**: Moved from local const to edge_processing.h #define for configurability. Firmware builds clean at 843 KB.
