Recompile workflow lock files (frontmatter hash mismatch)

[mnriem]

The agentic workflow lock files are out of sync with their source .md files — the frontmatter hashes no longer match.

Affected files:

• .github/workflows/add-community-preset.lock.yml
• .github/workflows/add-community-extension.lock.yml

Fix: Run gh aw compile to regenerate both lock files.
