The direct "ref:<id>" picker for a widget-level reference (VHS_LoadVideo's
"video", etc.) forced reselecting the field by hand every time the
underlying reference file changed. Adds the same numbered indirection
Input Sources already gives sockets: "Reference video 1" is whatever is
marked first among video references, not a specific file, so re-marking
in the Media Bin re-points the widget with no node-config change.
Adversarial review of this addition, run to convergence, found and fixed
in order:
- a real installed file whose name collided with the sentinel pattern
("ref#video:1", "ref:whatever") could be silently hijacked instead of
used as-is -- fixed by having a literal installed choice always win,
identically in the builder and the picker;
- the self-heal fallback for a stale plain value could reach into
reference-slot space and silently attach a live Media Bin dependency
the user never picked;
- fixing that reopened the underlying onChange(undefined) hole the
fallback chain had been papering over, wiping a stale plain value
outright when nothing was installed -- restored the original
choices-only self-heal invariant explicitly;
- a reference-capable widget could be added to a Linked Inputs group,
whose own value editor builds a spec with no ref_kind -- silently
wiping the shared reference across every member on next render.
Simplest safe fix: that kind of field doesn't link.
