Function handle_heal_project_spawn 

pub(crate) fn handle_heal_project_spawn(
    workspace: &Arc<Workspace>,
    project_name: &str,
    launch_settings: SessionLaunchSettings,
) -> Result<(), String>

The heal’s resume: the same spawn as handle_spawn_project, but it cannot open a seat the reader closed. A heal recovers a death; it is never an opening door.
