refactor: overhaul Docusaurus command and generation

- Rework `hero docusaurus` command to use local `cfg` files
- Scan and export doctree collections during site generation
- Fix `baseUrl` redirect path handling in `index.tsx`
- Add cycle detection for `play.include` in playbooks
- Improve site config processing to prevent duplicate items
