Patch Changes

• af9bda8: feat: pull in snapchain V16 protos (signers and scopes / gasless signers)

  Regenerates protobuf bindings against snapchain e8e89a3, the client
  surface for engine version V16 (LATEST_PROTOCOL_VERSION 10 → 11;
  ProtocolFeature::GaslessSigners gate). V16 activates testnet
  2026-04-28 20:00 UTC and mainnet 2026-05-07 17:00 UTC.

  • MESSAGE_TYPE_KEY_ADD (16) and MESSAGE_TYPE_KEY_REMOVE (17) on
    MessageType, plus KeyAddBody / KeyRemoveBody and corresponding
    KeyAddData / KeyAddMessage / KeyRemoveData / KeyRemoveMessage
    type narrowings and isKeyAdd* / isKeyRemove* typeguards in core.
  • Backfills the previously-missing isLendStorageData /
    isLendStorageMessage typeguards.
  • New unified signer surface in RPC: GetSigner and GetSignersByFid
    return both on-chain and off-chain (gasless) keys via SignerResponse
    and SignersByFidResponse. The pre-existing GetOnChainSigner and
    GetOnChainSignersByFid are now marked deprecated; existing callers
    are unaffected. The Signer proto message is re-exported from core
    as SignerInfo to disambiguate from the existing cryptographic
    Signer interface.
  • GetSignersByFid accepts a SignersByFidRequest so callers can
    request current per-FID nonce counters (current_user_nonce,
    requester_fid_nonces).
  • BlocksRequest.shard_id is removed (server already ignored it; field
    number 1 is reserved on the wire).

  Adds LendStorage*, KeyAdd*, and KeyRemove* factories plus runtime
  tests for the new typeguards.
