Add an MCP Streamable HTTP server with token authentication, screenshot capture, keyboard, and mouse tools. Introduce shared control-mode and input-control coordination so MCP, PicoClaw, and local HID paths serialize ownership safely. Integrate PicoClaw gateway/runtime control handoff with PID-managed startup and focused unit coverage.
