- Add `retention run` command (ports Invoke-RetentionPolicy.ps1): purges
old artifact/log dirs with aggressive mode when disk space is low.
- Add `template backup` command (ports Backup-CITemplate.ps1): 7z -mx=1
compressed archives in /var/lib/ci/backups/, prunes to keep-count=3,
stops/restarts act-runner.service around the copy.
- Update ci-retention-policy.service and ci-backup-template.service to use
Python; pwsh is no longer required on the Linux host.
- Fix ci-watch-runner-health.service: pass --service-name act-runner
(Linux service name, not Windows act_runner default).
- Fix _list_orphans in vm.py: wrap is_dir() inside the OSError try block
so a stat() failure on an entry is silently skipped rather than raised.
- Mark B5 complete in PhaseB-user-checklist.md.
