Handles the final step of getting your feature branch onto main, with two paths depending on whether CI is available. When CI is up, it opens a PR with auto-merge enabled. When CI is down or frozen, it runs a mandatory code review agent on the diff first, then does a local shallow-clone merge. Either way, it validates your code, determines the target branch from plan files or reflog, and cleans up the worktree afterward. The prerequisites are strict: you must be off main, validation must pass, and all tasks must be complete. No self-rescue if CI fails after the PR is open, it just stops and asks you what to do.
