Run your spec and capture its behavior as a new version.

Executes every input in the spec and stores the outputs together with the full
runtime capture - model identity and version, sampling settings, and the resolved
prompt - as an automatically named version (v1, v2, ...). Run 'dow init' first to
scaffold a spec. Configured evaluators run automatically, and
re-committing an unchanged spec measures non-determinism. Use --from to branch from
an earlier version.

@examples
dow commit
dow commit -m "lower temperature"
dow commit --from v1
