## PR-Codex overview

This PR focuses on removing the `Bridge.routes` functionality and the `useBridgeRoutes` hook from the codebase, along with related references and documentation updates in various files.

### Detailed summary

- Deleted `Routes.ts`, `Routes.test.ts`, and `useBridgeRoutes.ts` files.
- Removed references to `Bridge.routes` in multiple `.mdx` files and sidebar components.
- Updated `index.ts` to stop exporting `routes`.
- Adjusted `useSendTransactionCore` to use `Bridge.tokens` instead of `Bridge.routes`.
- Removed the `PriceComparator` class and associated methods for route comparison.
