Overview

Multi-select trigger for PhlexKit::Combobox that shows each checked option as a removable chip: the controller renders ComboboxBadge-style chips into the badge container, backspace in the empty field removes the last one, and clear_button: true adds a ComboboxClearButton. Ported from ruby_ui's RubyUI::ComboboxBadgeTrigger; upstream shipped the markup without controller support, so the badge rendering / backspace-removal / clear-all behaviour is PhlexKit's completion of it. Keyboard actions live here because focus stays in this field (see ComboboxInputTrigger). See combobox.rb.
