092229c6 - fix(GridLayout): support RTL direction for drop target positioning (#9848)

fix(GridLayout): support RTL direction for drop target positioning (#9848) * fix(GridLayout): support RTL direction for drop target positioning GridLayout.getDropTargetFromPoint() computes 'before'/'after' drop positions using x-coordinates, but has no awareness of layout direction. In RTL locales, the Virtualizer positions items using CSS 'right' with the layout rect's x value as the right-offset, while pointer coordinates remain in visual (left-origin) space. This mismatch causes drop targets to be inverted — dragging an item to the right of another shows a 'before' indicator instead of 'after'. This commit adds an optional 'direction' property to GridLayoutOptions. When set to 'rtl', getDropTargetFromPoint flips the x-coordinate to match the layout coordinate system before computing drop positions. Consumers can pass direction via useLayoutOptions() in a GridLayout subclass: class LocaleAwareGridLayout extends GridLayout { useLayoutOptions() { const { direction } = useLocale(); return { direction }; } } * test(GridLayout): add unit tests for RTL drop target positioning Tests getDropTargetFromPoint with both LTR and RTL directions to verify that drop targets (before/after) are computed correctly in multi-column grids. Also tests that single-column layouts are unaffected by direction and that empty layouts return a root drop target. * fix(GridLayout): auto-determine direction via useLocale() in RAC wrapper Instead of requiring consumers to subclass GridLayout and pass direction manually, create a RAC wrapper (like TableLayout) that calls useLocale() internally via useLayoutOptions(). The base layout in react-stately still accepts direction as an explicit option for non-RAC consumers. * fix: use public GridLayout import * add test story * fix tests, missing size mock * chore: apply oxfmt formatting Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix formatting --------- Co-authored-by: Daniel Lu <dl1644@gmail.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
