Note

Medium Risk
Adds new request/response fields for managed auth connections (auto_reauth, health_checks), which may change behavior for clients that rely on default auth-connection settings. Remaining changes are mostly version bumps and doc/CI workflow pinning.

Overview
Bumps the SDK release to 0.55.0 (version files, manifest, changelog, and OpenAPI spec metadata).

Extends managed auth connection create/update (sync + async) and related types to support new configuration flags auto_reauth and health_checks, and updates tests accordingly.

Polishes start_url parameter descriptions across browser session/pool resources and response types, and pins GitHub Actions used in CI/release workflows to specific commit SHAs.
