autoloop: Stop

Cleanly terminate a self-revising loop. Appends a ## DONE section with timestamp + reason, sends a PushNotification summarizing final state, and stops scheduling new wake-ups. The next /loop firing will see the DONE marker and exit without acting.

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

Arguments

• Positional (optional): reason string. Defaults to "user-requested stop".
• --keep-forensics (flag, optional): retain the state directory after stop instead of archiving + removing it. Default behavior since Wave 2: cleanup tarball is created and <state_dir> is rm -rf'd. Pass this flag if you need to inspect heartbeat.json or revision-log/ after stop.
