Develop (#13)

* Refactor carbon-server service in docker-compose.yml to use pre-built image and remove unnecessary build context and volume mounts

* Enhance performance and security features:
- Update compiler flags for better optimization and security.
- Implement MIME type caching for improved response handling.
- Introduce worker thread pool for efficient connection management.
- Optimize socket settings for low latency and enhanced performance.
- Add support for CPU affinity in worker threads.
- Implement graceful shutdown for worker threads during cleanup.

* Optimize HTTP response handling and increase request limits for improved performance

* Add gzip compression support for HTTP responses

* Implement Keep-Alive support for HTTP connections with timeout handling
Why is it not merging like this huh
