Fixed

• Crash when occlusion ray and entity eye position coincide — If a camera and an entity eye position were at the same point (degenerate geometry, e.g. some Voxy LOD entities or extreme camera clipping), to.subtract(origin).normalize() produced a NaN direction vector. Minecraft's DDA raycast then diverged into undefined behaviour, freezing or crashing the render thread. rayCast() now short-circuits immediately when the squared distance between endpoints is below 1 × 10⁻⁶, and adds a secondary NaN guard after each passable-block step.
