lars e6e0eb22bf Implement Phase 2: secondary particle prediction ...

Two-stage factorisation: Stage 1 predicts 9D primary kinematics + n_sec
classification head (COND_DIM reduced to 8, dropping n_sec/e_sec inputs);
Stage 2 (SecondaryDecoder) generates K_MAX=15 secondary slots via masked
flow matching over (stick_logit, local_dir, type_emb) conditioned on Stage 1
output. Joint training with combined loss L_s1 + λ_nsec*L_nsec + λ_s2*L_s2.
