## Summary
Adds a comprehensive GitHub Actions workflow that automatically responds
to pull requests with AI-powered code reviews and automated fixes. The
workflow handles PR labeling, manages retry logic (up to 3 retries), and
integrates with Claude Code for automated problem resolution.

## Test plan
- Verify the workflow is properly formatted and no syntax errors exist
- Check that the workflow triggers on the correct events
(pull_request_target with labels and workflow_run)
- Verify that only trusted maintainers (wwwillchen, wwwillchen-bot) can
trigger the workflow
- Test the retry logic by checking label transitions (cc:request →
cc:pending → cc:request:N)
- Confirm the workflow creates meaningful git commits through Claude
Code
- Verify proper cleanup of labels when max retries (4 total) are reached

> [!NOTE]
> **Low Risk**
> Small workflow change, but it affects automation that can push to PR
branches; failure modes are limited to CI/labeling behavior.
> 
> **Overview**
> The `PR Review Responder` workflow now runs an additional Claude Code
step after `/dyad:pr-fix` to push any local commits that may have been
created but not pushed (via a new `/dyad:fast-push` invocation).
> 
> This reduces cases where the workflow would proceed to “check if
commits were pushed” and label transitions without the PR branch
actually being updated.
