Copy and templates now emit the clean caption PLUS an "_ai2go" sidecar holding the full editor box
list (groups, parenting, ids, names, collapse/lock). Paste/import/template-load restores from it when
present, so AI2Go→AI2Go round-trips losslessly. KJNodes (and the model) ignore the unknown key, so:
- AI2Go → KJ: pastes as a normal flat scene.
- KJ → AI2Go: no sidecar → imports flat (as before).
- AI2Go → AI2Go: hierarchy + groups fully preserved.
The sidecar is added only when there's hierarchy/groups to keep (plain scenes stay clean). The Python
`prompt` output and the token estimate use the clean caption — the sidecar is clipboard/template-only.
JS parses clean.
