Scaffolding: docs repo governance

Suggested structure

• Keep only user-facing docs; versioned under versions/<release>/ with latest symlink.
• Top-level README.md describing navigation + contribution rules.
• STYLE.md for voice, formatting, code fences.

Automation to add

• GitHub Action: docs-lint.yml (markdownlint, link checker, front-matter validator).
• Phage policy: enforce versioned docs, forbid archive/ folders, ensure landing page exists.
• Branch protection: require docs-lint + link-check statuses.

Cleanup tasks

• Delete archived/AI-dump folders; move any keepers into versions/vNEXT.
• Add versions.json manifest with latest tag pointer.
• Add docs/STRUCTURE.md and docs/CONTRIBUTING.md.
