Eliminate direct @plebbit/plebbit-js (8.7MB) imports from all UI components by replacing
Plebbit.getShortAddress() with a local get-short-address utility. Add Vite manual chunks for
plebbit-js, plebbit-react-hooks, and react-spring/use-gesture. Fix catalog CLS by matching
skeleton to wrapper dimensions. Lazy-load ChallengeModal and ReplyModal. Add failed-URL cache
to useFetchGifFirstFrame, optimize useHide selector, and memoize useFeed options in mod-queue.
