🌋 Volcano Eruption Dynamics — 2D Ballistic Blocks and Column Height

2D side-view companion of the volcano eruption sim: ballistic blocks with quadratic drag in an exponential atmosphere, a landing-distance histogram, range versus block size, and Mastin's eruption-column height law; checked against vacuum range and terminal speed.
