Function new_session_with_layout 

pub fn new_session_with_layout(session: &str, layout: &str) -> Result<()>

Creates a new Zellij session with the given layout and attaches to it.

Must be called from outside Zellij — the process replaces the current terminal with the new session (interactive, inherited stdio).

Errors

• Invoking zellij fails or exits with a nonzero exit status.
