Refactor `route` function for improved performance and error handling

- Normalized URL path by removing trailing slashes for consistent matching.
- Added proper 404 response when a route is not found, including the requested path in the error message.
- Enhanced error handling to return a 500 Internal Server Error for unexpected exceptions.
- Prepared for potential optimization by suggesting the use of a `Map` for faster route lookups.
- Improved code readability and maintainability.
