"""cc-ci recipe-report launcher — one-shot agent that runs /recipe-report after the weekly upgrade.

The report agent's model is configured SEPARATELY from the upgrader (so e.g. the upgrader runs on
sonnet while the report is written by opus). Defaults: REPORT_MODEL=opus, REPORT_BACKEND=claude.

Usage:
  launch-report.py start [DATE]   use-or-create the session; runs /recipe-report [DATE]
  launch-report.py fresh [DATE]   always start a new session
  launch-report.py stop           kill the session
  launch-report.py status         show session state

Env: REPORT_MODEL (default opus), REPORT_BACKEND (default claude), REPORT_SESSION, REPORT_DIR.
