Held STT start-of-speech events were replayed while agent playout still appeared active, which rearmed the gate. Mark playout inactive first and release any stale gate or buffered transcripts at agent speech end.

Replayed STT speech-start events observed active agent playout and rearmed the transcript gate. End playout before replay and release stale buffered events at agent speech end. Ports livekit/agents#7083 at c27a885e.
RunContext.disallow_interruptions() could leave its current speech paused by false-interruption handling. A tool that awaited session.say() then deadlocked behind the paused parent. Route the state change through the owning activity so it releases only that handle's pause.

Problem: False or overlapping speech could leave held transcripts or a parent response active after the interruption ended. The stale state produced concurrent speaking spans and could block uninterruptible tool speech, preventing transfers.
Behavior: Resolve playout before replaying held STT events. When a tool disables interruptions, release its parent response from any false-interruption pause so queued speech can run.
