AI Summary

A performance-oriented patch release for the XYFlow system library that optimizes zooming and panning behavior, along with fixes for dark mode rendering and edge cases in node positioning.

Key Highlights

Cached zoom pane extent to prevent synchronous layout recalculations during panning and pinching.
Fixed incorrect fill color for the background pattern in dark mode.
Fixed `fitView` to correctly handle hidden nodes that declare intrinsic sizes.
Added safety checks to prevent errors when clamping node positions.

### 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.
