Issue :
Every time searchTerm changes, SearchProvider:

1. fetches the entire search index JSON again
2. flattens it
3. creates a brand new Fuse instance
4. runs the search

Typing "createVector" = 13 requests to the same en.json. No debounce,
no abort, no caching. The Fuse index is expensive to build and should
be created once per locale, not per keystroke.

There's also a race condition, no AbortController means a slow response
for "col" can resolve after "color" and overwrite the results.

Should be:

• fetch + build Fuse once per locale change, store in a ref
• separate effect just for running fuse.search(searchTerm)
• debounce the search (~250ms)
• AbortController on the fetch with cleanup

Easy to reproduce: open /search/, DevTools Network tab, type anything
fast and watch duplicate requests pile up.
