feat: Redirect all docs links to new MkDocs documentation

- Update Navigation "Docs" link to point to /framework-docs/
- Replace /docs page with redirect notice to /framework-docs/
- Update home page wizard guide links to point to MkDocs sections
- Auto-redirect users to new docs after 3 seconds

This ensures users always see the comprehensive v1.8.0-beta
wizard documentation (45+ guides) instead of the deprecated
docs page.
