Review PR Findings

Review and address pull request review findings on the current branch.

Workflow

1. Find the pull request

Run:

git branch --show-current
gh pr list --head <branch> --json number,title,state,url

• If no pull request exists, tell the user and ask whether to create one.
• If multiple pull requests exist, show the options and ask which number to use.
• If exactly one exists, continue with it.
