Wipes today's briefing messages (keeps the conversation row) and optionally re-fires the compilation slot to regenerate. Pairs with the new POST /api/briefing/reset-today backend route. Also drops the stale briefing_mode reference from trigger_briefing's docstring now that legacy mode is gone. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
