Implement pull request review comments API

- Add get_pull_request_reviews() method to fetch all PR reviews
- Add get_review_comments() method to fetch comments for specific review
- Update get_pull_request_comments() to use proper review-based flow:
  1. Download all reviews of the pull request
  2. Download all comments for each review
  3. Return aggregated comments from all reviews
- Add review context (review_id, review_state) to comments for debugging
- Add error handling to continue processing if individual review fails
- Update tests to match current Claude Code command implementation
