install backlog-mcp-server on VS Code

Requires Node 18+ on your system so npx can fetch the package 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 backlog-mcp-server.

{
  "servers": {
    "backlog": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "backlog-mcp-server"
      ],
      "env": {
        "BACKLOG_DOMAIN": "your-domain.backlog.com",
        "BACKLOG_API_KEY": "your-api-key"
      }
    }
  }
}
