Implement SSZ-REST transport for all Engine API methods: - new_payload (v3/v4) - forkchoice_updated (v3) - get_payload (v3/v4/v5) - exchange_capabilities (v1) - get_blobs (v1, stub) New CLI flag --ssz-rest-url enables SSZ-REST with automatic fallback to JSON-RPC on network errors. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- new_payload → POST /engine/v{N}/payloads
- forkchoice_updated → POST /engine/v3/forkchoice
- get_payload → GET /engine/v{N}/payloads/{payload_id}
- exchange_capabilities → POST /engine/v1/capabilities
- Error responses now text/plain instead of JSON
- Added do_get_request/do_http for GET support

Per execution-apis PR sigp#764 spec: - PayloadStatus.latest_valid_hash: List[Hash32, 1] - ForkchoiceUpdatedResponse.payload_id: List[Bytes8, 1] - ForkchoiceUpdatedRequest.payload_attributes: List[PayloadAttributes, 1] - Remove unused UnknownSelector/ServerError variants Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
SSZ-REST URL is now derived from the execution endpoint (same host:port). The EL serves SSZ-REST on the engine port under /engine/* paths. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
