Validate a TAO DAFT Dataset

Quick start

tao-daft validate <format> --path <dataset-or-parent-dir>

<format> is a positional subcommand (e.g. metropolis-v3.0, cosmos-reason-v1.0); --path is required. Discover supported formats and per-format flags via tao-daft validate --help and the leaf --help (see "CLI conventions" below).
