fix: restore pre-commit, CGO_ENABLED, gohtml template

- Add CGO_ENABLED=1 to CI test step for race detection
- Fix docker job needs (remove dependency-review, only runs on PRs)
- Restore .pre-commit-config.yaml for local dev safety
- Rename html_template.html to .gohtml (conventional extension)
- Add GitHub URL and default branch info to AGENTS.md
- Add .dprint.jsonc config
- Various formatting normalization
