Make PR Review Monitoring the Default

[ptr727]

Summary

• Make pull request creation start the review loop by default.
• Require a foreground review status read followed by a bounded background wait.
• Continue through findings, fixes, replies, resolution, and re-review until green.
• Permit stopping or altering the loop only on explicit maintainer instruction.
• Expand the skill trigger and AGENTS routing so the rule fires when a PR opens.
• Regenerate the GitHub Copilot and Claude Code skill distributions.

Why

The review-loop procedure was correct after it started, but neither the skill trigger nor the PR-creation handoff required it to start. An agent could therefore open a draft PR, report the URL, and stop before requesting or monitoring review.

Pull request overview

This PR updates the fleet PR review-loop contract so that opening a pull request explicitly starts (and does not end) the default review-monitoring loop, requiring an initial foreground status read followed by a bounded background wait, and propagates that rule through the skill distributions.

Changes:

• Updated GOVERNANCE.md PR Review Etiquette to state that PR creation starts the review loop and that the loop must be actively monitored by default.
• Expanded AGENTS.md routing so the PR review conduct rule is triggered when opening a pull request.
• Updated and re-distributed the pr-review-conduct skill content across the Copilot/agents/Claude skill trees, including the regenerated source digest.
