Agent Identity & Delegation Chain Verifier

Verifies the two most-cited emerging agent-identity primitives in sequence: a did:webvh DID log's hash-chain and update-key authorization, then an ACDC credential chain's SAID integrity and issuer-to-issuee edge linkage back to a stated root AID. Verify-only across both steps; neither tool operates witness/registry infrastructure.
