/**
 * Function type for sending a message to LlmChat.
 *
 * Implementation detail: The returned function is "attachable".
 * LlmChat will call the internal `_attach` method (if present) to bind
 * its real message handler. Messages sent before attachment are queued
 * and flushed after attachment.

/**
 * Hook to create a sendMessage function for an <LlmChat/> component WITHOUT needing any React Context.
 *
 * Usage pattern:
 * ```tsx
 * const sendMessage = useSendMessageToLlmChat();
 * return (
 *   <>
 *     <button onClick={() => sendMessage('Hello!')}>Hello</button>
 *     <LlmChat llmTools={llmTools} sendMessage={sendMessage} />
 *   </>
 * );
 * ```
 *
 * - No provider wrapping needed.
 * - Safe to call before the <LlmChat/> mounts (messages will be queued).
 * - Keeps DRY by letting <LlmChat/> reuse its internal `handleMessage` logic.
