warelay 1.2.1\n\n- Heartbeat: warelay heartbeat now supports --message/--body for manual sends on web or twilio, with --dry-run to preview payloads.\n- Media handling: MIME-first detection (magic bytes > headers > extension) so images/audio/video/doc send correctly even with wrong suffixes, and images still recompress under caps.\n- Hosting/inbound: hosted and saved media files are renamed with the detected extension, ensuring correct Content-Type for Twilio/web round-trips (including Baileys inbound saves).\n- Docs/tests: changelog and image docs updated; added coverage for inbound media extension preservation.\n
