Overview

Single-field trigger for PhlexKit::Combobox — the input doubles as the filter (autocomplete style): focusing or clicking opens the popover, typing filters, arrows/enter pick, and the chosen option's text becomes the field value. Ported from ruby_ui's RubyUI::ComboboxInputTrigger; upstream shipped the markup without controller support, so the behaviour (open-on-focus, keyboard nav from the field, selection reflection) is PhlexKit's completion of it. Keyboard actions live here because focus stays in this field — the popover's own bindings only fire for the button+search layout. See combobox.rb.
