install gemini-cli 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 gemini-cli.

{
  "servers": {
    "gemini-cli": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@google/gemini-cli"
      ]
    }
  }
}
