Commit: Sergey Kostyaev <sskostyaev@gmail.com>

    Add functionality to send last user message
    
    Added a new function `ellama-get-last-user-message` to extract the
    last unsent user message from the current session buffer. Also, added
    a new command `ellama-chat-send-last-message` to interactively send
    this last message.
