Follow-up to the salvaged #71756: instead of webhook importing cron's private _is_cron_silence_response, the loose autonomous-lane matcher now lives in gateway/response_filters.py as is_autonomous_silence_response, sharing LIVE_GATEWAY_SILENT_MARKERS with the interactive exact-marker rule so the marker sets can never drift. Cron and webhook both delegate to it. Interactive gateway behavior unchanged.
