danielhanchen 331fa7e560 llama: load qwen4exp (Qwen3.8-Flash-Next) hparams and tensors
Adds LLM_ARCH_QWEN4EXP with its hparams and tensor loading. The graph
comes in the next commit; this makes the model load and report correct
metadata.

- hyper-connections set n_embd_out_impl = hc_count * n_embd, so the
  residual stream is 4x wide and there is no output_norm: the final
  mixer's hc_norm is the last norm in the model.
- registered as hybrid and given the same recurrent/attention memory
  filters as Qwen3-Next and Qwen3.5.
- reuses the existing indexer, per_layer_token_embd, SSM and
  compress_ratios keys as-is.
- the PLE table row count is read back from the file rather than
  recomputing the vocab padding rule.

llama-model-loader gains UINT64 array support. That branch previously
threw, so no existing caller changes behaviour; it is needed because the
PLE hash multipliers do not fit in int32.
