Make SAF-T an executable release contract.

A pinned ruleset and deterministic machine-readable output turn representative exports into regression tests.

2. Run the supported Saftlint CLI release locally.
3. Fail only on the severities your team has reviewed.
4. Store the result and receipt as build artefacts.

No free automation API

The web endpoint is an internal, rate-limited implementation detail. Repeatable automated use belongs in Saftlint CLI.
