 * - StructuredToolInterface (LangChain StructuredTool)
 * - RunnableToolLike (Runnable converted to tool via .asTool())
 * - StructuredToolParams (minimal tool definition with name, schema, extras)
 * - ToolDefinition (OpenAI format: { type: "function", function: {...} })
 * - Record<string, any> (generic object with name and parameters)
 *
 * The AI SDK expects tools as a Record<string, Tool> where each Tool
 * is created using the tool() helper function.
