Commit Message

fix: use length-delimited hashing in ComputeBlockDataHash (#97)

#### Type of change

- Bug fix

#### Description

  ComputeBlockDataHash previously concatenated all data items and hashed
  the result, which is not cryptographically safe — different sets of
  items with different boundaries can produce the same hash.

  Switch to length-delimited serialization where each item is prefixed
  with its 4-byte big-endian length before hashing. This matches the
  orderer's BatchedRequests.Digest() computation.
