[aw] Agent Documentation Maintainer failed

### Workflow Failure

**Workflow:** [Agent Documentation Maintainer](https://github.com/githubnext/ado-aw/blob/main/.github/workflows/doc-freshness-check.md)
**Branch:** main
**Run:** https://github.com/githubnext/ado-aw/actions/runs/34562717291

> [!WARNING]
> **Engine Failure**: The `copilot` engine terminated unexpectedly.

**Last agent output:**
```
└ 11 lines…
● List open PRs for githubnext/ado-aw (shell) 20s
│ cd /home/runner/work/ado-aw/ado-aw && github list_pull_requests --owner githubnext --repo ado-aw

└ 15 lines…
Multiple open PRs already target the exact same gap: `container_runtime.rs` missing from AGENTS.md's architecture tree. Let me verify this is indeed a real gap and check if there's anything else to find, since that one is already covered extensively.
● Check container_runtime.rs existence and AGENTS.md mention (shell)
│ cd /home/runner/work/ado-aw/ado-aw && find src -iname "container_runtime*"

Start with .github/workflows/doc-freshness-check.md and the linked failed run, then inspect AGENTS.md alongside src/container_runtime.rs as indicated by the agent output. Confirm why the documentation-maintainer agent terminated and whether the existing PRs already address the reported architecture-tree gap. Done means the failure is resolved without duplicating work already underway.
