Enhance the response interface to include all required properties and methods

[3m1n3nc3]

This PR provides methods for setting headers, managing status codes, sending different content types, and offering convenience helpers, along with a complete and expressive Response API that is comparable to Laravel’s response helpers, while being fully typed for TypeScript.

• Review the existing Response implementation.
• Add missing properties and methods.
• Update TypeScript types and ensure strict typing.
• Add inline JSDoc for each method.
• Write comprehensive unit tests.
• Verify compatibility with current kernel and middleware logic.

Closes #72
