Note

Medium Risk
Adds a new browsers.curl API surface and adjusts multipart file-extraction logic; both could affect request serialization and compatibility with the backend if the schema/paths differ.

Overview
Adds a new browser HTTP passthrough API via POST /browsers/{id}/curl, exposing client.browsers.curl(...) (sync/async) with new request/response types (BrowserCurlParams, BrowserCurlResponse) and documentation/tests wiring, including raw/streaming response wrappers.

Fixes multipart file extraction by changing extract_files to remove fields even when the remaining traversal is only "<array>" markers (enabling correct handling of top-level file arrays), with a new unit test covering this case.

Bumps package and release metadata to 0.50.0 and updates the changelog/spec stats accordingly.
