New MCP servers added to the gateway stack:
- memory-bank-mcp (port 8700): Persistent key-value memory storage with tags, categories, and search
- puppeteer-mcp (port 8800): Headless browser automation via Pyppeteer (navigate, screenshot, click, JS eval, PDF gen)
- sequential-thinking-mcp (port 8900): Structured step-by-step reasoning with branching hypotheses and synthesis
- docker-mcp (port 9000): Docker container/image/network/volume management via Docker socket
All servers follow the existing Python/FastMCP pattern with streamable-http transport.
docker-compose.yml updated with service definitions and gateway backend routes.
