verify — run checks, emit a machine contract

Run the project's verification checks (test / lint / build, plus an optional dynamic observation) and report the result as a stable, versioned JSON contract — the same envelope code-review emits in mode:agent, so lfg and other callers read either skill the same way. This skill is the dynamic (does-it-run) counterpart to code-review's static (is-it-sound) review.

Always invoke this skill fully-qualified as tunan:verify — a host may ship an unnamespaced verify; never call it bare.

Invocation
