🌊 Submarine Sonar Descent - 2D Sound Ray Tracing and Sound-Speed Profile

2D companion of the submarine sonar descent simulation: acoustic rays bend through a depth-dependent sound-speed profile (deep-ocean channel, thermocline, shadow zones) with travel-time graphs, checked against Snell invariance and circular-arc ray theory.
