fix(nodes): linked text review round for #343

- A legacy frontend Primitive linked to an editor's text or the Pair's
  negative now runs with its value: the graphToPrompt wrapper and the queue
  hook fill it in (through virtual reroutes), in new and pre-#343 workflows.
- Moving a linked text and releasing it on the editor keeps it on `text`:
  a link being moved counts as free, as the frontend counts it.
- A link dropped on a prompt box (or its link note) fills that box's input,
  so the Pair's Negative prompt box takes `negative_text` (Classic through
  getInputOnPos, Nodes 2.0 through the box's slot key).
- Only exact STRING links are steered; wildcards keep the frontend choice.
- A linked Classic text box gives its row back and gets it back on
  disconnect; the PromptManagerText note uses the theme colour.
- The metadata parsers map positional widget values through the widget
  table when an editor's widget-bound inputs do not line up with it.
- Real-host cases for the legacy Primitive (new and saved workflows, a real
  Run), the moved link, the Negative box, paste/clone/undo and Split.
