feat(caller): env-gated Session A VAD hardening for noisy environments#59

Conversation
Separate Session A (caller) VAD/noise config from Session B so the caller path can be tuned independently — the caller has no echo gating, unlike the callee, so shared thresholds were the wrong knob. - Session A dedicated settings: session_a_vad_* + session_a_noise_reduction - Optional OpenAI input noise_reduction (near_field) on audio.input - Optional server VAD for the relay caller (continuous streaming) via NEXT_PUBLIC_RELAY_CALLER_VAD=server; relay wires speech_stopped -> response All features default OFF (noise_reduction=none, caller VAD=client) so a main deploy is behavior-neutral. Enable per-env for booth testing: SESSION_A_NOISE_REDUCTION=near_field (relay) NEXT_PUBLIC_RELAY_CALLER_VAD=server (web) WARNING: the server-VAD caller path is UNTESTED — verify turn-taking on a live call before enabling. Session B (callee) pipeline is unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
