Prepare PR

Overview

Prepare a PR branch for merge with review fixes, green gates, and an updated head branch.

Inputs

• Ask for PR number or URL.
• If missing, auto-detect from conversation.
• If ambiguous, ask.

Safety

• Never push to main or origin/main. Push only to the PR head branch.
• Never run git push without specifying remote and branch explicitly. Do not run bare git push.
• Do not run gateway stop commands. Do not kill processes. Do not touch port 18792.
• Do not run git clean -fdx.
• Do not run git add -A or git add .. Stage only specific files changed.
