-- file-search — fuzzy search panel, fzf as the matching subsystem.
--
-- On open the search folder is walked once with `find` into a cache file
-- (excluded directory names are pruned, hidden entries too unless enabled);
-- after that every keystroke runs `fzf --filter=<query>` over the cache, so
-- typing stays responsive even on large trees. Results update live; picking
-- one opens it with the system MIME association (xdg-open) — directories
-- open in the file manager. Enter opens the top match.
--
-- The index is rebuilt when the panel opens with changed settings, or on
-- demand via the refresh button. The bar widget mirrors the panel's open
-- state through the shared "file_search_open" state key.
