Implement remote MCP server deployment capabilities

- Add HTTP/JSON-RPC server for remote MCP access
- Configure domain and authentication via environment variables
- Create comprehensive remote deployment documentation
- Support both local (stdio) and remote (HTTP) deployment modes
- Add PM2 and Nginx configuration examples
- Update README with remote server instructions

The server can now be deployed on a VM (e.g., Hetzner) and accessed
from Claude Desktop over HTTPS using the configured domain.
