Cryptographic guarantees

All attestation primitives use:

• Ed25519 — signing key generated at backend startup (or loaded from HIVE_ATTEST_PRIVATE_KEY_B64URL)
• RFC 8785 JCS — deterministic canonicalization for all signing operations
• SHA-256 — payload hashing, Merkle tree nodes
• No mocked signatures — every signature is a real 64-byte Ed25519 output
