Add patch for NodeGraphQt PySide6 6.7+ compatibility

The setSelectionArea() API changed in PySide6 6.7 - it now requires an ItemSelectionOperation parameter before ItemSelectionMode. Files added: - patches/nodegraphqt_pyside6_compat.patch: Git-style patch file - patches/UPSTREAM_ISSUE.md: Issue report for upstream project - scripts/patch_nodegraphqt.py: Script to auto-apply the patch The patch fixes rubber band selection errors when dragging in the node graph viewer. Run after pip install: python scripts/patch_nodegraphqt.py Co-Authored-By: Claude Opus 4.5 <[email protected]>

+"""Patch NodeGraphQt for PySide6 6.7+ compatibility.
+
+The setSelectionArea() API changed in PySide6 6.7 to require an
+ItemSelectionOperation parameter. This script patches the installed
+NodeGraphQt package to work with newer PySide6 versions.
+
+Issue: setSelectionArea(path, mode) -> setSelectionArea(path, operation, mode)
+
+Usage:
+    python scripts/patch_nodegraphqt.py
+
+This can be run after `pip install NodeGraphQt-QuiltiX-fork[pyside6]`
