* claim: #9719 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Dynamics: rigid-body solver core with joints, gravity and springs (#9719) A new L1 crate, solidcraft-dynamics (geom only): rigid bodies in maximal coordinates, joint constraint equations with analytic Jacobians for rigid, revolute, slider, cylindrical, planar and ball joints, gravity, linear spring-dampers and constant loads; the index-1 equations of motion solved through a rank-revealing Schur complement (repeated joint equations are solved, not refused); RK4 and Dormand-Prince 5(4) with position and velocity projection; joint values, rates, reactions and energies at every output sample; caps on bodies, joints, rows, steps and samples; Result errors only.
