Documents and enforces rules for closed-not-merged PR reconciliation, direct-master-push prevention, and issue label cleanup. Rules added: - Explicit definitions for Merged, Landed, Closed-not-merged, and Reconciled. - A PR is done only when Gitea reports it merged or reconciliation proves content is present on master. - Direct push to master is forbidden except as a documented recovery exception. - PRs closed but not merged trigger the reconciliation process. - Branch and worktree cleanup is forbidden until merge or reconciliation is confirmed. - Final reports require PR metadata and Git content verification. Closes #51.
