FLUX.2 Klein Base 4B AlphaGRPO checkpoint

This is a complete native Diffusers Flux2KleinPipeline. The EMA LoRA is already merged into the transformer, so FAR and PEFT are not required for inference.

Source checkpoint: step_1000.pt

Training profile: 512px, 20 rollout steps, CFG 4, AlphaGRPO DVReward.
