* 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.

* fix(rpc): satisfy architecture-migration compat-marker guard
Put the removal condition on the RUSTFS_COMPAT_TODO marker line itself, and
stop backticking env-var/metric names in the cleanup-register entry so the
guard's id extractor only sees the task-id.

* perf(ecstore): seek encrypted multipart Range GETs to the covering part boundary on the Legacy rio v1 backend
Phase A of https://github.com/rustfs/backlog/issues/1316. Encrypted Range GETs on the default (non rio-v2) backend previously planned storage_offset=0, storage_length=oi.size and discarded the decrypted prefix, so a small Range on a large SSE object read, erasure-decoded, and decrypted the whole object. Eligible multipart objects now seek to the covering part boundary using only the per-part size/actual_size metadata facts; the multipart decrypt reader already handles streams starting at any part boundary, so rio and the on-disk format are untouched. Single-part objects, compressed payloads, defective parts tables, and zero-length ranges keep the previous full read, and RUSTFS_ENCRYPTED_RANGE_SEEK=false restores it globally. A new histogram rustfs_get_encrypted_range_read_amplification plus a full|part_seek path counter record the physical/plaintext amplification at the ReadPlan decision point.
* fix(ecstore): guard encrypted multipart range seeks
* fix(io-metrics): align encrypted range metric names with the rustfs_io_ prefix
Every other metric in rustfs-io-metrics uses the rustfs_io_ prefix; the
two encrypted-range-seek metrics were the only exception. Rename before
first release so dashboards never see the unprefixed names.
