Smithy CLI v1.39.0

1.39.0 (2023-09-20)

Features

• Refactored smithy-rules-engine significantly in an effort to improve validation, separate
  AWS and non-AWS concerns, add a specification, and more. General notes are provided in
  individual commit messages. The format of the rules documents have not changed, meaning a
  successful migration to the refactored codebase will involve no changes to code generated
  for an SDK client (#1855)
• Added Sha1 checksum to ResolvedArtifacts (#1979)
• Relaxed Content-Length in unset union payloads protocol tests (#1984)

Documentation

• Updated example by keeping operation list from previous examples (#1981)
