* feat(rpc): bind canonical body digest into internode mutating disk RPC signatures Binds a domain-separated, length-prefixed canonical request-body digest into the v2 HMAC signature scope for every mutating NodeService disk RPC, so an on-path attacker on the default-plaintext internode channel can no longer tamper with a mutation payload (or strip the msgpack `_bin` field to force the JSON fallback decode) without invalidating the signature. Covers 13 mutating disk RPCs: RenameData, DeleteVersion, DeleteVersions, WriteMetadata, UpdateMetadata, WriteAll, Delete, DeletePaths, RenameFile, RenamePart, DeleteVolume, MakeVolume, MakeVolumes. The digest covers both the msgpack `_bin` payloads and their JSON compatibility copies. Gated fail-open by default (RUSTFS_INTERNODE_RPC_BODY_DIGEST_STRICT) with a convergence counter, so rolling upgrades are byte-for-byte unaffected; the replay-cache capacity is now configurable and overflow fails closed with a metric.
