Note

Low Risk
Primarily a generated SDK release with additive fields and documentation/metadata updates; existing integrations should remain compatible aside from consumers who rely on strict field lists or assumptions about viewport validation.

Overview
Releases v0.34.0 (updates manifest, internal.PackageVersion, README install snippet, changelog, and tracked OpenAPI spec metadata).

API model updates: adds error_code to managed auth session/flow types (including SSE follow events) to expose machine-readable failure reasons, and extends AppAction with input_schema/output_schema JSON Schema payloads.

Browser viewport change: updates viewport documentation/expectations across browser, invocation, and pool types to indicate arbitrary viewport dimensions are accepted (with a list of known-good presets).
