fix: Restructure fork review workflow to avoid PR branch checkout

- Create isolated review context directory to prevent PR detection
- Move diff to changes.patch file in review-context directory
- Add explicit REVIEW_INSTRUCTIONS.md file for guidance
- Use standard 'prompt' parameter instead of 'override_prompt'
- This approach should prevent Claude Action from auto-detecting PR context
