Mixed_CFM: absorb Unified_CFM primitives; remove Unified_CFM

Browse Source 
Mixed_CFM was loading AdaLNBlock / SinusoidalTimeEmb / _sinkhorn_coupling
and flow-feature helpers from Unified_CFM via importlib spec hacks. Pulled
those symbols into Mixed_CFM/_layers.py (model primitives) and inlined
the flow-feature loader helpers into Mixed_CFM/data.py, then deleted
Unified_CFM/ entirely along with three dead aggregate shell scripts whose
referenced eval entry point (artifacts/verify_2026_04_24/) was already gone.

Verified: historic janus_iscxtor2016_seed42 checkpoint re-evaluated under
the absorbed code reproduces all 10 phase1 AUROC scores to 6 decimals;
same-seed retrain converges to within +/-0.001 on terminal_norm (residual
drift is CUDA non-determinism in MultiheadAttention + Sinkhorn argmax,
not the absorption).
