Subject: rc.d: gemset auto-detection, occurrence regeneration command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Derive rvm gemset path from .ruby-version and .ruby-gemset in the
  app directory, with fallback to current hardcoded values — no more
  manual rc.d edits on gemset changes
- New extra command: service cccms regenerate_occurrences
- Poststart staleness check: regenerates occurrences when marker file
  /var/db/cccms_occurrences_regenerated is missing or older than one
  year; runs only after successful server start, synchronously for
  error visibility

Deployment note: updated script must be manually copied to
/usr/local/etc/rc.d/cccms on live.
