Fetch Unresolved PR Review Comments

Uses GitHub's GraphQL API to fetch only the unresolved review-thread comments from a pull request, grouped by file.

When to Use

• You need only the unresolved review comments from a PR.
• You want to filter out feedback that has already been resolved.

Instructions

1. Get the PR URL:

   • First check for environment variables: if PR_NUMBER and GITHUB_REPOSITORY are set, construct the URL as https://github.com/${GITHUB_REPOSITORY}/pull/${PR_NUMBER}.
   • Otherwise, use gh pr view --json url -q '.url' to get the current branch's PR URL.
