refactor!: add Synapsis for dependency resolution and injection

- Remove Middleware class and custom callback handling logic.
- Implement Synapsis as a dependency injection container for automatic
resolution.
- Refactor Router to use Synapsis for process route callbacks and not found
handler.
- Update Request to remove middleware-specific properties and use
Router::$currentParams for path parameters.
