Mouse position now determines facing direction as a client-side float. WASD remapped: W=toward cursor, S=away, A/D=strafe. Facing octant derived from mouse angle and sent to server via SET_FACING action only when it changes. EntityRenderer facing indicator uses continuous angle for smooth rotation. SimBridge test mode updated to handle SetFacing. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
