Remove NATIVE_NUMERIC_WIDGET_NAMES exclusion list (rotate_deg, scale, strength, width, height, rotate). Excluded widgets were left visible as native LiteGraph sliders at the bottom of nodes, creating vertical empty space and duplicate UI (notably CameraShake/Transform/Spherize). Also includes prior session work: P1-P4 UX improvements, video preview anti-blink/anti-stutter fixes in source.ts, README and REFACTO docs cleanup.
