ReferenceError: WIDTH is not defined when saving any JS/TS collection

[Braintelligence]

Editing a field of a record in a TypeScript data file (e.g. export const themen = [{ id, titel, text }, …]) and saving throws ReferenceError: WIDTH is not defined.

electron/jsCollections.js references WIDTH in literal() (lines 287 and 295) but never declares it:

if (pad.length + oneLine.length + 1 <= WIDTH && !oneLine.includes('\n')) return oneLine;
// …
if (!val.includes('\n') && inner.length + key.length + 2 + val.length + 1 > WIDTH) {

Any collection whose rows are objects is affected; only arrays of plain strings or numbers never reach that branch.

Fix: declare the constant next to ID_KEY. The comment above the usage already says it should match Prettier's default printWidth:

// Prettier's default printWidth; used by literal() to decide when a record
// stays on one line.
const WIDTH = 80;

With that in place, replaceCollection() writes the record back correctly, long strings dropping to their own line as intended:

  {
    id: "software",
    titel: "Software, Automatisierung und Auswertung",
    text:
      "Warenwirtschaft, Rechnungswesen, komplexe Automatisierungen sowie Berichte, Gutachten, Kataloge und barrierefreie PDFs.",
  },

Reproduces on main at e5e63d8 and in the shipped 0.1.23 build. There are currently no tests for jsCollections.js, which is why it went unnoticed.
