algovoi-keystone-vc

Emit an AlgoVoi keystone decision as a W3C Verifiable Credential (Data Model 2.0). The credential uses our own KeystoneExecutionCredential type and @context, so it needs no registration. The content-addressed executionRef is the credentialSubject.id; a consumer recomputes it from the subject with only JCS (RFC 8785) + SHA-256, so the credential is content-bound before any signature suite is applied. Signing (a DataIntegrityProof such as eddsa-jcs-2022) is the issuer's step.
