### Testing Checklist

- [x] Extension installs successfully via download URL
- [x] All commands execute without errors
- [x] Documentation is complete and accurate
- [x] No security vulnerabilities identified
- [x] Tested on at least one real project

### Submission Requirements

- [x] Valid `extension.yml` manifest included
- [x] README.md with installation and usage instructions
- [x] LICENSE file included
- [x] GitHub release created with version tag
- [x] All command files exist and are properly formatted
- [x] Extension ID follows naming conventions (lowercase-with-hyphens)

### Testing Details

The exact published ZIP was installed from the release URL into a freshly initialized disposable Spec Kit project with the current `specify` CLI. Installation completed without manifest errors, and `specify extension list` reported DocGuard v0.40.5 with **12 commands and 5 hooks**. The installed `extension.yml`, `commands/fix.md`, and `commands/review.md` are byte-for-byte identical to the tagged release sources; the command-contract suite also checks unique names, same-named routing, file existence, frontmatter, and complete declaration of every shipped command.

The exact release commit passed **1,794 tests on Node.js 18, 20, 22, and 24**, DocGuard's self-check, and the OSV supply-chain scan. The publication workflow successfully produced the GitHub release, npm and PyPI packages, GHCR image, extension ZIP, and MCPB artifact. Product behavior has also been exercised against the repository's pinned public-project benchmark corpus and prior cross-project field tests.

### Example Usage

```bash
# Install the extension
specify extension add docguard --from https://github.com/raccioly/docguard/releases/download/v0.40.5/spec-kit-docguard-v0.40.5.zip

# Run the documentation quality gate
/speckit.docguard.guard
```

### Additional Context

**This updates the existing catalog entry (`docguard`)**. Please bump that entry to v0.40.5 and use the new download URL rather than adding a duplicate.

v0.40.5 corrects the Spec Kit manifest contract: all 12 shipped commands are declared exactly once, `fix` and `review` route to their matching command files, and the manifest description matches the proposed catalog entry while remaining below Spec Kit's 200-character limit.

- Release: https://github.com/raccioly/docguard/releases/tag/v0.40.5
- Release PR: https://github.com/raccioly/docguard/pull/394
- Manifest correction: https://github.com/raccioly/docguard/pull/392
- Release workflow: https://github.com/raccioly/docguard/actions/runs/34926468263

Locate the existing docguard catalog entry and compare it with the proposed catalog entry in the issue. Update that entry to v0.40.5 and the new download URL, without adding a duplicate; confirm the manifest details, command and hook counts, and links match the submission.
