docs: add Docker installation and configuration options

- Replace development MCP config with Docker-based configuration
- Add Docker build instructions in installation section
- Provide two deployment options: uv (production) and Docker (containerized)
- Docker config uses 'docker run --rm -i' for proper MCP stdio communication
- Include image build commands for local Docker deployment

Fixes duplicate uv configurations by offering Docker alternative
