[WALLET-87] Update x401-node to spec 0.2.0#5
Merged
Conversation
Rework the SDK for x401 0.2.0: flat payload carrying the Verifier-composed Digital Credentials request at presentation_requirements, VP Artifact with inline result or presentation_uri reference, and removal of the Verifier Challenge (delete challenge.ts; keep createEncryptor as a standalone primitive). Add a spec-conformance harness pinned to the upstream spec: vendored Appendix C JSON Schema + extracted examples, sync/normative-ledger scripts, schema and fixture round-trip tests, a requirement->code map, and an upgrade runbook.
