test(experiments): validate C6 cross-operator attestation in software#24

Conversation
Compose the SEV-SNP verifier, measurement pinning, and the sealed channel into a two-operator harness: two operators in separate trust domains, each binding its sealed-channel public key into an attestation report. The experiment and CI test demonstrate independent keys, mutual attestation, confidential cross-operator delegation (seal to the counterparty's attested key), and binary-swap detection (a changed measurement is rejected with AttestationFailed). Report-signature and chain paths use synthetic vectors (a genuine report needs SEV-SNP hardware), matching how cmcp validates its cross-org claim; real hardware end to end and the live A2A transport binding remain open. Shared synthetic-report helpers moved to conftest. All six claims (C1-C6) are now validated experiments. Suite: 92 passed, 99%.

Validates the final claim, C6, completing the claim suite. A two-operator harness composes the pieces already built (SEV-SNP verifier + measurement pinning + sealed channel):
