Active-Set Reduced Differentiable QP Layer

Replace full-KKT implicit differentiation through a constrained quadratic-program layer with differentiation through only the equality constraints and inequalities active at the optimum. The forward solver still enforces all constraints, but the backward linear system scales with the active-set size rather than the total number of inequalities.

Constructive Two-View Gauge Initialization

Initialize latent coordinate-frame parameters analytically from two temporally separated neural predictions instead of starting joint optimization from arbitrary translation and orientation. This removes the continuous gauge before backpropagation and should prevent EKF-like or gradient-based failures caused by large yaw and position initialization errors.
