[aw] PR Documentation Check hit engine rate limit (HTTP 429)

### Workflow Failure

**Workflow:** [PR Documentation Check](https://github.com/microsoft/aspire/blob/main/.github/workflows/pr-docs-check.md)
**Branch:** dev/sebastienros/centralize-python-sdk-validation
**Run:** https://github.com/microsoft/aspire/actions/runs/32552675579

> [!WARNING]
> **Engine Rate Limited (HTTP 429)**: The `copilot` engine hit provider rate limits and could not complete this run.

This signal was detected from engine runtime logs/OTLP telemetry.

**What to do next**
- Retry the workflow after a short delay.
- If this keeps happening, reduce concurrent workflow volume or review provider quota/rate-limit policies.

### Action Required

**Assign this issue to an agent** to debug and fix the issue.

Debug with any coding agent

Use this prompt with any coding agent (GitHub Copilot, Claude, Gemini, etc.):

````
Debug the agentic workflow failure using https://raw.githubusercontent.com/github/gh-aw/main/debug.md

The failed workflow run is at https://github.com/microsoft/aspire/actions/runs/32552675579
````

Manually invoke the agent

Debug this workflow failure using your favorite Agent CLI and the `agentic-workflows` prompt.

- Start your agent
- Load the `agentic-workflows` skill from `.github/skills/agentic-workflows/SKILL.md` or
- Type `debug the agentic workflow pr-docs-check failure in https://github.com/microsoft/aspire/actions/runs/32552675579`

> [!TIP]
>
> Stop reporting this workflow as a failure
>
> To stop a workflow from creating failure issues, set `report-failure-as-issue: false` in its frontmatter:
> ```yaml
> safe-outputs:
> report-failure-as-issue: false
> ```

Start with .github/workflows/pr-docs-check.md, the failed run logs, and the agentic-workflows skill or debug.md referenced in the issue. Confirm why the copilot engine received HTTP 429 and determine whether the workflow should handle the rate limit or stop reporting it as a failure. Done means the workflow behavior is corrected and a repeat run no longer produces the same actionable failure.
