Blame for scripts/test-in-editor.mjs

#!/usr/bin/env node
/* test-in-editor.mjs: run the extension inside a REAL VS Code or VSCodium.
 *
 *   node scripts/test-in-editor.mjs                 finds VSCodium (flatpak or on PATH) or VS Code
 *   DSSL_EDITOR="code" node scripts/test-in-editor.mjs
 *
 * It opens a real editor window (a throwaway profile, so yours is untouched), loads the extension
 * from this checkout, runs dssl-vscode/test/host/index.js in the extension host, and prints the
 * results. Needs a display, so it is not part of test-all.mjs.
  * The UI half (typing, hover, the designer panel) is scripts/test-editor-ui.mjs. */
