James Anderson fffda16106 feat(dev): React-based runtime error overlay (#1029) ...

Surfaces three error sources that previously only reached the console:
React render errors caught by an error.tsx boundary (onCaughtError),
render errors with no boundary above them (onUncaughtError), and plain
script errors / unhandled promise rejections via window listeners.

The overlay renders into a separate createRoot mounted on a detached div
appended to body, so it survives an unmount of the main hydrateRoot tree
— necessary because most errors we want to surface take that tree down.

Includes a /dev-overlay-test fixture and Playwright spec covering all
three error sources, dismiss, and prev/next pagination across multiple
errors.
