Note

Medium Risk
Medium risk because it adds a new browsers.curl API surface and changes how multipart request bodies are copied/extracted across several endpoints, which could affect file upload behavior and request payload mutation.

Overview
Bumps the SDK to v0.50.0 (metadata, pyproject.toml, CHANGELOG.md, and api.md).

Adds POST /browsers/{id}/curl to the browsers resource (sync/async + raw/streaming wrappers), along with new BrowserCurlParams/BrowserCurlResponse types and associated tests/docs.

Fixes and optimizes multipart file handling by introducing deepcopy_with_paths (copy only containers on file paths), removing deepcopy_minimal, and adjusting extract_files to correctly pop fields when paths end with "<array>" markers; updates multiple upload-style endpoints (browsers extensions, browser fs uploads, deployments, extensions) to use the new copy helper. Also adds optional hint to managed-auth field models and updates project docs to remove “paid plan” gating language.
