chore: bump version, update changelog (#221)

* feat: enable container query support for Columns component

Update the Columns component to use a `--cols` CSS variable for dynamic column counting. It now supports container query breakpoints like `@[]` and `@sm` in addition to media query breakpoints, allowing for responsive column wrapping based on the parent container's width. A new `InsideContainer` Storybook story demonstrates this behavior.
