Fixes #58807. A compressed-tensors pack-quantized checkpoint that ships its MTP head dense (plain mtp.*.weight names in a separate bf16 shard) crashes at weight load: Qwen3_5MultiTokenPredictor builds its Linears from the target quant config, so the loader expects packed names (weight_packed) the checkpoint never had, and the weight-map walk dies with "no module or parameter named fc.weight". Detect the dense MTP head from the checkpoint itself: read the safetensors index via the same repo-file channel used for recipe.yaml (local cache first, Hub download as fallback). If any mtp.* tensor carries a quantization artifact suffix the head is properly quantized and nothing changes; if every mtp.* entry is a plain .weight the whole predictor builds unquantized (fc and layers), mirroring the existing modelopt_fp4 and GPTQ dynamic carve-outs. Single-file checkpoints have no index and keep current behavior; NVFP4 checkpoints are unaffected (their mtp.layers.* carry artifacts).
