merge: focus-visible rings + live search count (#69)

Keyboard focus was invisible on the objects-table sort headers and
page-size select, breadcrumb links, the external-URI link, and the
combobox input/clear/trigger. Apply the shared focusRing helper in app
code and the kit's inline focus-visible classes (matching input.tsx)
in ui/combobox.

Make the search result count a role="status" live region so screen
readers announce updated counts while typing; the existing search test
now asserts the count through getByRole("status").

Closes #69
