declare function getLastUserMessage(clientId: string): Promise<string>;
Retrieves the content of the most recent user message from a client's session history.
This function fetches the raw history for a specified client using getRawHistory and finds the last entry where the role is "user" and the mode
is "user". It is wrapped in beginContext for a clean execution environment and logs the operation if enabled via GLOBAL_CONFIG. The result is
the content of the last user message as a string, or null if no matching user message exists in the history.
