install plane-mcp-server on VS Code

Requires Python 3.10+ and uvx (install with `pipx install uv`) so the package can be resolved on first run. 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 plane-mcp-server.

{
  "servers": {
    "plane": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "plane-mcp-server",
        "stdio"
      ],
      "env": {
        "PLANE_API_KEY": "<your-api-key>",
        "PLANE_WORKSPACE_SLUG": "<your-workspace-slug>",
        "PLANE_BASE_URL": "https://api.plane.so"
      }
    }
  }
}
