PR Review Loop

Autonomously drive a PR (and its sibling backport PRs) through this loop:

pause CI → self-review the diff → request Copilot review → fix every finding
        → re-review (loop until clean)
        → relaunch tests → on failure: fix + re-enter loop → on success: append " [ready]"

The goal is a PR that is green and has no outstanding Copilot findings, marked ready for human review — without ever merging it.

When to use

• The user wants a hands-off "get this PR reviewed and green" cycle.
• A change spans a main PR + one or more backport-*-to-stable/* PRs that must stay in sync.
