AI Summary

This patch release focuses on performance optimization and bug fixes. It introduces a cache for the zoom pane extent to prevent forced synchronous layouts during panning and pinching, while also fixing several edge cases related to node positioning, view fitting, and dark mode styling.

Key Highlights

Cache zoom pane extent to prevent forced synchronous layouts during panning and pinching
Fix `fitView` with `includeHiddenNodes` to properly handle nodes with intrinsic sizes
Correct dark mode background pattern fill color
Prevent errors when clamping positions if the parent node is missing
Ensure `onPanZoomEnd` fires correctly for scroll-wheel interactions

New Features

Performance optimization: Caching zoom pane extent
Bug fix: `fitView` functionality with intrinsic size nodes
Bug fix: Dark mode styling
Bug fix: Parent node position clamping
UX fix: Pan/Zoom end event handling

### Patch Changes

-   [#5850](https://github.com/xyflow/xyflow/pull/5850) [`c707267`](https://github.com/xyflow/xyflow/commit/c707267bc80bc954fdc69a08c9e00c98068dd613) - Cache the zoom pane extent so panning and pinching no longer force a synchronous layout.


-   [#5839](https://github.com/xyflow/xyflow/pull/5839) [`0c0cebc`](https://github.com/xyflow/xyflow/commit/0c0cebc08cc34d2852d1ea429df638732b3edf68) - Use correct fill color for bg pattern in dark mode


-   [#5851](https://github.com/xyflow/xyflow/pull/5851) [`56cf3b0`](https://github.com/xyflow/xyflow/commit/56cf3b00369a680a71743e4fb277db26e861d4b0) - Fix `fitView` with `includeHiddenNodes` ignoring hidden nodes that declare an intrinsic size (`width`/`height`/`initialWidth`/`initialHeight`) but were never measured


-   [#5845](https://github.com/xyflow/xyflow/pull/5845) [`a01bb6b`](https://github.com/xyflow/xyflow/commit/a01bb6bf51e2de4eeee052187f3ce533c0e77754) - Check if parent node is in node lookup before clamp the position to prevent throwing an error.


-   [#5849](https://github.com/xyflow/xyflow/pull/5849) [`9b3f390`](https://github.com/xyflow/xyflow/commit/9b3f390e21c1801832449389b069c4e5a13b4d7f) - Always fire `onPanZoomEnd` when `onPanZoomStart` was fired due to a pan-on-scroll wheel tick


-   [#5837](https://github.com/xyflow/xyflow/pull/5837) [`cdfcbeb`](https://github.com/xyflow/xyflow/commit/cdfcbeb9618437b2e7c35336db157e36a5a0731e) - Check for element existence and type before checking property existence in node/edge typeguards.
