Function invoke_agent_with_session 

pub async fn invoke_agent_with_session(
    agent: &str,
    model: &str,
    context: &str,
    message: &str,
    session_uuid: Option<&str>,
    resume: bool,
) -> Result<InvokeResult>

Invoke an agent one-shot with --session-id or --resume for conversation continuity.

For claude-compatible agents (claude, kimi, minimax), passes --session-id <uuid> when creating a new session, or --resume <uuid> when continuing an existing one. Other agents get a plain one-shot call.
