feat: react router support

Support react-router-dom:

• Same generouted routing conventions w/ nested layouts
• Route-based loader
• Route-based action

The exported Routes component can be found in each integration file at src/react-location.tsx and src/react-router.tsx.

All latest updates (except docs) were already pushed to the main branch, you can find the file-based routes core/config at src/core.ts.

The core exports two functions to generate the routes and the preserved routes, and used in the current (and upcoming) integrations.
