local-bench Core Text v1 public suite

This bundle redistributes the packaged v1 public item sets:
- MMLU-Pro by TIGER-Lab, dataset license MIT.
- IFBench_test by AllenAI/Ai2, dataset license ODC-BY-1.0.
- TC-JSON v1, a local-bench-authored JSON tool-calling bench with a
  BFCL-derived single-turn backbone, distributed under Apache-2.0.

The local-bench scorer also includes IFEval-derived verifier code under
Apache-2.0; that code license is included for scorer provenance.

IFBench caveat: the upstream dataset card states that use should follow Ai2's
Responsible Use Guidelines and that the dataset includes output data generated
from third-party models subject to separate terms.
