feat(http): enhance type safety and extend route context

- Refactor HttpKernel and related interfaces to support generic contexts.
- Add typed query parameters, route params, and state to IContext.
- Introduce HttpMethod type for stricter HTTP method validation.
- Update RouteBuilder and middleware to handle generic contexts.
- Improve test cases to verify compatibility with new types.
