test: ignore animation-frame teardown errors; add dev VS Code task

framer-motion/framesync (and animejs) schedule rAF frames that can fire after a
test's jsdom env is torn down, throwing "window is not defined" as a flaky
unhandled error (framesync is imported inside framer-motion, so it can't be
vi.mock'd). Set dangerouslyIgnoreUnhandledErrors so CI is stable. Add a
"Dev: Vite + Electron" VS Code task.
