lars 44b0a92e67 Add WGAN-GP mode as a throwaway fast-eval experiment
Adds --mode wgan alongside flow/ddpm: both stages get a WGAN-GP
generator/critic pair (giant.model.wgan) instead of flow matching, so
inference is a single forward pass per stage rather than a 10-step ODE
integration — the fast-eval architecture noted in the roadmap.
predict/rollout auto-detect the mode from the checkpoint's model_config.
Best-checkpoint selection for wgan uses marginal-KL against the EMA
generators every epoch, since a critic loss isn't a monotone quality
signal. --router is not supported together with --mode wgan.
