Module kimi_k3_loader 

2026-09-25: The Kimi K3 ModelWeightLoader: binds BF16 or FP32 checkpoints, and packed MXFP4 experts only when K3_ALLOW_MXFP4=1.

Owner: model-engine Kimi K3 loader. Invariants:

• Every load_* method except load_mtp_weights (which returns Ok(None)) calls refuse_mxfp4 before it binds anything.
