OpenRouter built-in server tool: consults a higher-intelligence advisor model (any OpenRouter model) for guidance mid-generation and returns its response. The advisor may run as a sub-agent with its own tools. Include multiple entries to offer several named advisors; at most one entry may omit `name` to act as the default advisor.
