egutierrez	42957d10f6	fix(shaders_lab): node drag was overwritten by SetNodePosition each frame ... Previously SetNodePosition was called after EndNode every frame, which reset any drag the user had done. Now the initial position is set once per editor_uid (tracked in a static unordered_set), and the editor owns the position afterwards. GetNodePosition at end-of-frame keeps step state in sync for future persistence. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-24 22:04:07 +02:00
