/**
 * pl_editor (drawing-sheet editor) programmatic-open regression.
 *
 * Guards the web-app wiring added for pl_editor:
 *   1. the generic kicadOpenFile() embind hook (wasm/bindings/pl_editor_embind.cpp)
 *      — PL_EDITOR_FRAME overrides OpenProjectFiles, so a .kicad_wks can be opened
 *      deterministically without UI automation, and
 *   2. the seeded KiCad config that skips the first-run STARTWIZARD (the harness
 *      now seeds it in preRun, matching the web app's boot.ts) — without it the
 *      wizard's modal loop wedges the boot and no file can load.
 *
 * Strategy mirrors eeschema-load.spec.ts: write a minimal .kicad_wks into MEMFS,
 * call Module.kicadOpenFile(), and poll the editor title. GREEN once it shows the
 * file name; also asserts no setup wizard is visible and no WASM abort fired.
