Subject: [PATCH] fix: exclude compaction notices from TTS transcript
 accumulation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add isCompactionNotice flag to ReplyPayload and set it on both the
compaction start notice (agent-runner-execution.ts) and the completion
notice (agent-runner.ts). dispatch-from-config.ts skips accumulation
into accumulatedBlockText when the flag is set, so compaction status
lines (🧹 / ✅) are never synthesised into the fallback TTS audio for
block-streaming runs with tts.mode=final.
