[Enhancement] Strengthen Existing HTTP Methods & Add Support for Additional Methods

# Description:
We need to enhance the support of the existing HTTP methods and expand our HTTP server's capabilities by adding new methods. This is an essential step in making the server more feature-complete, robust, and secure.

# Problem:
Currently, the HTTP server only supports a limited number of methods (`POST`, `PUT`, `DELETE`, `CONNECT`, `OPTIONS`, `TRACE`, `PATCH`). While this covers a decent range of use cases, there are certain HTTP methods and scenarios that are not adequately supported or optimized for scalability and security.

- **Existing methods need improvements**: Some of the methods listed above have basic functionality, but they lack:
- Proper error handling and security validation.
- Full compliance with HTTP standards and best practices.
- Edge case coverage (e.g., handling missing headers, body validation, etc.).

- **Missing methods**: We currently do not support other important methods like `HEAD`, which are widely used in RESTful applications. Adding these methods will make the server more versatile and production-ready.

### Proposal:
We want contributors to focus on the following key points:
1. **Strengthening Existing Methods**:
- **Robust Error Handling**: Ensure each method properly handles erroneous input, unexpected headers, invalid request formats, and more.
- **Security Enhancements**: Incorporate input validation, CSRF protections (where relevant), and proper use of HTTP status codes.
- **Performance Optimization**: Check for redundant operations and optimize for speed, especially in high-traffic scenarios.
- **Thorough Testing**: Write comprehensive unit and integration tests to cover both typical and edge cases for each method.
- **Standards Compliance**: Ensure each method adheres to HTTP/1.1 and HTTP/2 specifications.

2. **Adding New Methods**:
- **HEAD**: Similar to `GET` but without the response body, it should be handled efficiently.
- **Other Methods**: Depending on your expertise, suggest other methods you think would benefit the project, such as `PATCH` improvements, `PUT` enhancements, etc.

### How to Contribute:
- **Step 1**: Before jumping into implementation, **please describe in detail how you plan to implement this**. Outline your approach to improving the existing methods, adding new methods, and ensuring security and performance improvements. The more detailed, the better!
- **Step 2**: **Review the `README.md`** to get a deep understanding of the project's current scope, goals, and vision. This will help align your contribution with the overall direction of the project.
- **Step 3**: **Review the `CONTRIBUTING.md`** to understand the contribution guidelines. This will help ensure that your code follows our standards, making it easier for us to review and merge your pull request.

### Key Considerations:
1. **Security First**: Every method must be reviewed and enhanced with security in mind (e.g., SQL injection prevention, safe handling of user input).
2. **Error Handling**: Return appropriate HTTP status codes and meaningful error messages for invalid or incomplete requests.
3. **Modular Design**: Ensure that the logic for each method is modular and can be easily extended or modified.
4. **Testing**: Comprehensive test coverage is required. Unit and integration tests should cover both happy paths and edge cases.
5. **Documentation**: Document the changes and new features clearly in the code, and update the `README.md` if necessary.

### Acceptance Criteria:
- Detailed plan for implementation (to be submitted before starting).
- Updated support for `POST`, `PUT`, `DELETE`, `CONNECT`, `OPTIONS`, `TRACE`, `PATCH` with error handling and security improvements.
- Proper implementation of new methods (`HEAD`, and others as needed).
- Tests to ensure that all methods behave as expected.
- Adherence to HTTP standards and guidelines.

### Notes for Contributors:
- If you're interested in tackling this issue, **please comment below with your detailed implementation plan before starting any development**. This will help us ensure that everyone's on the same page and prevent duplicated work.
- Don’t forget to **read both the `README.md` and `CONTRIBUTING.md`** files thoroughly to align with the project’s vision and follow the contribution process smoothly.

Looking forward to your ideas and contributions! Let’s make this server more robust, secure, and feature-rich together! 😊
