The bare-list combo (3861b6c) fixed the widget type, but the optional
socket's hollow ring still draws: LiteGraph draws optional sockets as
HollowCircle and core VAELoader.vae_name (required) draws none. The
backend socketless option-dict flag is ineffective in frontend v1.49.x
(addComboWidget only copies values/advanced/hidden onto widget.options,
so the !c?.options?.socketless gate never fires). The Director's JS
install() now nulls the preview_tiny_vae socket shape on create + load
-- same look as VAELoader, socket stays connectable. Drop the dead
socketless flag; update tests + docs.
