## Summary
Enhanced the PR review responder workflow to support multiple retry
iterations (up to 3) for Claude Code review requests. The workflow now
tracks retry attempts using numbered labels (`cc:request:N`) and
automatically re-requests reviews when new commits are pushed, while
escalating to human review after max retries are exhausted.

## Key Changes
- **Retry tracking**: Replaced simple `cc:request` label detection with
support for `cc:request` (initial) and `cc:request:N` (re-request
iterations) labels
- **Max retry guard**: Added logic to prevent infinite loops by capping
retries at 3 attempts; PRs reaching this limit are labeled with
`cc:needs-human-review` for manual intervention
- **Dynamic label management**: Updated label removal/addition to use
the current label dynamically instead of hardcoding `cc:request`
- **Conditional re-triggering**: Split the final label update into two
paths:
- If commits were pushed: increment the request count and apply
`cc:request:N` to auto-re-request review
  - If no commits were pushed: apply `cc:done` label to mark completion
- **Output tracking**: Added `commits_pushed` output to the retrigger
step to enable conditional downstream steps
- **Label creation**: Ensured next iteration labels are created before
being applied to PRs

## Implementation Details
- Request count is parsed from label names using regex matching
(`/^cc:request:(\d+)$/`)
- The workflow maintains state through GitHub labels, allowing it to
resume correctly even if interrupted
- Label creation attempts are wrapped in try-catch to gracefully handle
existing labels
- The retry loop is bounded at 3 iterations to prevent runaway
automation

<!-- CURSOR_SUMMARY -->

> [!NOTE]
> **Medium Risk**
> Changes a privileged GitHub Actions workflow’s control flow and label
automation, which could cause unexpected re-trigger loops or incorrect
PR state if misconfigured. Risk is bounded by the new max-retry guard
and explicit `commits_pushed` gating.
> 
> **Overview**
> Adds **bounded auto-retry support** to `pr-review-responder.yml` by
recognizing `cc:request` *and* numbered `cc:request:N` labels, tracking
the current iteration via step outputs.
> 
> When Claude pushes new commits, the workflow now emits a
`commits_pushed` output, creates the next `cc:request:N` label if
needed, and swaps `cc:pending` to the incremented request label to auto
re-request review; if no commits were pushed it continues to mark the PR
`cc:done`.
> 
> Introduces a **max retry guard (>=3)** that removes the current
request label and escalates the PR to `cc:needs-human-review` (creating
the label if missing) to prevent infinite automation loops.

## Summary by cubic
Adds an automatic re-request loop to the PR review responder so Claude
reviews are re-requested on new commits. Iterations are tracked with
cc:request:N labels (max 3), escalating to cc:needs-human-review at the
limit or cc:done if no new commits.

- **New Features**
- Detect and parse cc:request / cc:request:N; pick highest count; expose
request_count and current_label outputs.
- Use dynamic label management: remove current_label, add cc:pending
while processing.
- On new commits: create next cc:request:N, apply it, retrigger via
workflow_dispatch; set commits_pushed output.
  - On no commits: remove cc:pending and add cc:done.
- After 3 retries: remove current_label and cc:pending, add
cc:needs-human-review.
