Note

Medium Risk
Touches core streaming response construction by threading FinalRequestOptions into SSE stream classes, which could subtly affect streaming behavior or future option usage. The rest is a straightforward additive API parameter and release metadata updates.

Overview
Bumps the SDK to v0.38.0 (manifest, pyproject.toml, _version.py, changelog) and updates the recorded OpenAPI spec metadata.

Adds a query parameter to browsers.list (sync + async) to support searching browser sessions, including updating the generated params type and resource tests.

Internal streaming change: SSE Stream/AsyncStream now accept and retain FinalRequestOptions, with _response.py passing request options into constructed stream instances. Proxy env var tests are hardened by clearing other proxy-related environment variables before assertions.

Proxy env var set then immediately deleted on Windows

Low Severity

monkeypatch.setenv("HTTPS_PROXY", ...) is called before monkeypatch.delenv("https_proxy", ...). On Windows, os.environ is case-insensitive (all keys uppercased), so the delenv("https_proxy") call deletes the HTTPS_PROXY that was just set. This causes the test to fail on Windows. Moving setenv after all delenv calls would fix the ordering issue.
