feat(router): add excludeAction option for URL routing

- Add ExcludeAction field to target struct in routing configuration
- When excludeAction is true, skip appending action to URL path
- Provides flexibility for routing scenarios where action should not be part of URL path
- Maintains backward compatibility by defaulting to existing behavior

This change allows routing rules to be configured with excludeAction: true when the target URL should not have the action appended to its path.
