- useTasks debounced effect bailed when searchQuery transitioned back to
undefined (App passes `searchQuery || undefined`), so clearing the
input never refetched the unfiltered list. Track previous value via
ref and only skip the initial mount.
- FTS5 search used bare tokens (exact term match), so "frob" did not
match "frobnicator". Append `*` to each token (and to quoted tokens)
for prefix matching. LIKE fallback already did substring matching.
