Research direction

Look at the bregctl package command's code, likely in a src/cli/package.rs or similar module. Find where it builds and signs a successor package. Check the change plan against the predecessor for emptiness, and integrate the same error message used by apply.package.empty_plan. Run existing tests for the package command to ensure the new check works.

Description

area:breg enhancement

Gap

After #1353, bregctl apply reports a successor package with an empty change plan as apply.package.empty_plan instead of a binding refusal. bregctl package still builds and signs such a successor, so the operator only finds out when they apply it.

Request

Have bregctl package refuse, or at least warn about, a successor whose change plan against its predecessor is empty, using the same wording as apply.package.empty_plan. Check first whether any legitimate workflow needs an empty successor (for example, re-signing or re-keying only) before making this a hard refusal.

Follow-up from #1353.
