feature: Add Docker support

[FarDust]

This pull request introduces Docker support, improves environment configuration, and enhances code documentation and maintainability. Key changes include adding Docker-related files, refining .env usage, and updating Python code with type annotations and docstrings.

Docker Support:

• Added a Dockerfile to define the container environment, including dependencies and the command to run the MCP server.
• Introduced a docker-compose.yml file to simplify container orchestration, allowing easy setup with environment variables and automatic restarts.
• Updated README.md with instructions for running the MCP server using Docker, including steps for building, starting, and stopping the container.

Environment Configuration:

• Updated .dockerignore to exclude unnecessary files and directories, such as __pycache__, .env, and node_modules, from being copied into the Docker image.
• Removed the placeholder MEM0_API_KEY from the .env file and updated README.md with clearer instructions for setting up environment variables. [1] [2]

Code Improvements:

• Enhanced main.py with Python >3.11 style type annotations and added numpy-style docstrings to improve code readability and maintainability. [1] [2]
• Modified the server's CLI argument handling to use environment variables (HOST and PORT) as defaults, improving flexibility in deployment.
