feat: simplify docs by removing complex use case pages

- Remove convoluted use case pages (data-sync, upload-files, etc.)
- Eliminate 'Examples' section from navigation - now just Getting Started + Reference
- Keep use case descriptions in main page table for overview without links
- Focus documentation on essential guides: Overview, Quickstart, Debugging
- Point users to example app for complete implementation reference
- Cleaner, more focused documentation structure
