 Basic loop wiring:
 
 1. Connect `For Loop Start.flow` to `For Loop End.flow`.

 3. Connect the per-iteration output you want to keep, such as an image, latent,
    prompt, or metadata string, to `For Loop End.collect_value`.
 4. Optionally connect `For Loop Start.collected` to `For Loop End.collected`.
    If omitted, the end node uses the start collector internally.
 5. After the loop finishes, use `For Loop End.collected` as the combined output.
