[rolfbjarne]

Fixes #25605.

[Copilot]

Pull request overview

This pull request updates the repository’s compiled agentic workflow lock files to bring them back in sync with their corresponding .md sources (fixing the “lock file out of sync” failure reported in #25605) and refreshes the pinned tooling versions produced by gh aw compile.

Changes:

• Recompiled the code-radiator, macios-reviewer, and ci-postmortem workflow .lock.yml files with a newer gh-aw compiler output (schema v4 + updated component versions).
• Updated the workflows’ generated runtime scaffolding (artifact paths, restore steps for skills, updated error-detection step naming, etc.) as produced by the recompile.
• Updated .github/aw/actions-lock.json to the newer github/gh-aw-actions/setup@v0.77.5 entry.
