Feature: add responsive grid component
It would be useful to have a responsive grid component in gpui-kit, similar to [Ant Design Grid](https://ant.design/components/grid).
The main goal is to support breakpoint-based responsive layouts, for example:
- Automatically adjust the number of columns based on the available width.
- Support configurable breakpoints.
- Allow configuring the number of columns / span at different breakpoints.
- Support horizontal and vertical gaps.
- Avoid unnecessary empty space when the window size changes.
A typical use case would be displaying cards or other items in a responsive layout where the number of columns automatically changes as the available width changes.
For example:
Large window → 4 columns
Medium window → 3 columns
Small window → 2 columns
Very small → 1 columnIt would be great if gpui-kit could provide a reusable Grid component with behavior similar to Ant Design's Row / Col and breakpoint system.
Reference: https://ant.design/components/grid
For the card-grid example, GPUI already provides grid()/grid_cols() and container_query to choose the column count from the container's available width. That keeps the layout responsive inside a resizable panel as well as the whole window.
There is no dedicated Row/Col breakpoint component in Kit. The earlier layout discussion in #2967 covers the current direction: container widths rather than a global device-breakpoint system.
