 -   `GEMINI_TOOLS_DEFAULT_MODEL`: Sets a default LLM model specifically for tools hosted by the server (like `google_web_search`).
     -   **Purpose**: When a tool needs to invoke an LLM during its execution (e.g., to summarize search results), it will use the model specified by this variable. This allows you to use a different (potentially faster or cheaper) model for tool execution than for the main chat.
