Subject: [PATCH] fix(tts): skip TTS synthesis for compaction notices

Compaction start/completion notices carry isCompactionNotice: true on
the ReplyPayload.  Guard maybeApplyTtsToPayload() with an early return
so these informational UI signals are never synthesised as speech,
regardless of TTS mode or auto-mode configuration.

Addresses review feedback from jalehman on PR #38805.
