gsxdsm b3504f01a4 FN-8838: refresh automated PR heads before GitHub mutations

Refresh isolated automated PR heads against their target immediately before PR creation or merge.

- Rebase and lease-publish task and group heads at every automated GitHub boundary.
- Fail closed on concurrent head updates and reconcile retained refresh worktrees.
- Add lifecycle coverage and document the configurable integration remote.
