🎯 Dart Throw Lab: Release Angle, Flight Time & Gaussian Scatter

Throw darts at a regulation board with RK4 flight (gravity, drag, crosswind) and measure how Gaussian errors in release speed, angle and position grow into a tall elliptical group, with accuracy versus precision statistics and a distance/speed sweep checked against first-order error propagation.
