Host Test Layers

make test-host: fast deterministic unit/policy tests. Keep this limited to Seader-owned helpers, formatting, parsing, and ownership-policy logic.
make test-asn1-integration: narrow integration coverage for real ASN.1 ownership/free behavior.
make test-runtime-integration: narrow mock-based integration coverage for HF release ordering and final state publication.

Do not add generated ASN.1 or firmware-heavy runtime dependencies to make test-host unless they are already a supported part of that surface.
