Subject: [PATCH] fix: auto-reload on stale chunk load failure
 (vite:preloadError)

When a new deploy lands while a tab is open, lazy-loaded chunks (like
GifPicker) disappear because their content-hash filename changes. Vite
dispatches a vite:preloadError event in this case. We reload once and
clear the flag on successful load so future deploys can trigger again.
