fix: update API route to use catch-all pattern for clean URLs

- Rename API route from [slug] to [...slug] for catch-all routing
- Update API handler to join slug segments for scoped packages
- Remove encodeURIComponent from frontend API call

This fixes the 404 error when accessing tool pages with scoped package names.
The sync workers will need to run to populate README data for existing tools.
