Promote the previously-internal _AgentBackchannelOpportunityEvent to a public AgentBackchannelOpportunityEvent, emitted on AgentSession and dispatched to a new Agent.on_backchannel_opportunity() hook so agents can react to mid-turn pauses with acknowledgment phrases. Also fixes a race in AudioRecognition.update_vad(): the old VAD task was cancelled after the new one was already created/assigned, so a rapid update could have the old task's cleanup clobber the new stream/channel. Introduces a generation counter so a stale VAD task's events and cleanup are ignored once superseded. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
