Greptile Summary

This PR releases version 4.1.0 with SDK, packaging, and generated API updates.

  • Updated client request handling and retry behavior.
  • Added aiohttp and binary request support.
  • Updated serialization, parsing, and pydantic compatibility helpers.
  • Regenerated worker voice deployment types and resources.
  • Refreshed packaging metadata, CI, docs, and tests.

Confidence Score: 4/5

The GET request body path needs a fix before merging.

  • get_api_list(..., body=...) can still create GET requests with JSON data.
  • The changed request builder now removes that body before sending the request.
  • Other reviewed serialization, import, and generated resource changes look consistent with the inspected tests and call paths.

**GET Body Is Dropped**

When `get_api_list(..., body=...)` builds a GET request with `json_data`, this branch now skips all body arguments and removes `Content-Type`. Endpoints that require a JSON body for a GET list request will receive an empty request instead, which can return incorrect results or a server error.

fix(client): mark some request bodies as optional
Note that we still want to run tests, as these depend on the metadata.
Pin all GitHub Actions referenced in generated workflows (both
first-party `actions/*` and third-party) to immutable commit SHAs.
Updating pinned actions is now a deliberate codegen-side bump rather
than implicit on every workflow run.
