voice: audit + noise suppression toggle + stability fixes
Gateway: - transmitter.ts: cap backpressure queue at 500 chunks (prevents memory leak) - transmitter.ts: fix Redis race — assign redisSub AFTER subscribe completes - voice.handler.ts: static import Redis instead of dynamic (cleaner, no eval) Frontend: - mic-transmit.ts: MicAccessError with specific reasons (permission-denied, no-mic, timeout) - mic-transmit.ts: noiseSuppression option in getUserMedia constraints - mic-transmit.ts: proper DOMException handling for all getUserMedia failure modes - use-voice.ts: noiseSuppression state + toggleNoiseSuppression exposed - use-voice.ts: cleanup on unmount (stops transmitter, clears refs) - voice/view.tsx: noise suppression toggle button (ShieldCheck/ShieldOff icons) - voice/view.tsx: improved mic error toasts (permission denied / no mic specific) - voice/view.tsx: NS status in codec footer (NS_ACTIVE when enabled)
