--!nonstrict
-- file-search — bar widget that toggles the fuzzy search panel.
--
-- The panel (panel.luau) publishes its open state on the shared
-- "file_search_open" state key; the glyph lights up while it is open.
--
-- Click mapping:
--   Left click   — open/close the search panel
--   Right click  — open the search folder in the file manager
--
-- Middle click is deliberately not handled: every bar widget carries a built-in
-- `middle = settings-open-widget` binding, and a bound gesture is masked off the
-- widget's own input area, so an onMiddleClick here would never be called. The
-- manifest could reclaim it with `[widget.actions] middle = "none"` (plugin API
-- 14) — this plugin stays at the upstream behaviour instead.
