install qubes-mcp on VS Code

Requires the runtime declared in the upstream repo — check the README before running. VS Code (Copilot) uses a `servers` root key with an explicit `type` field — different from the `mcpServers` shape used by Claude Desktop and Cursor. Paste the config below, then follow the reload step to register qubes-mcp.

{
  "servers": {
    "qubes": {
      "type": "stdio",
      "command": "ssh",
      "args": [
        "-T",
        "user@<mcp-control-host>",
        "/home/user/qubes_mcp/.venv/bin/python",
        "-m",
        "qubes_mcp"
      ]
    }
  }
}
