Show HN: Base-GPUI: A GPUI port of Base UI headless components

Base-GPUI is a new port of Base UI's headless component library to GPUI, bringing rich, unstyled UI components with built-in accessibility and keyboard interaction to native applications. The library currently includes components like accordions, dialogs, buttons, checkboxes, tabs, and tooltips, with APIs designed specifically for GPUI's immediate-mode rendering model rather than being a direct React translation. The project is under active development with APIs subject to change before version 1.0.
