Note

Medium Risk
Mostly generated type/doc updates, but it also changes request body encoding behavior for application/x-www-form-urlencoded, which could affect how some API calls are serialized.

Overview
Bumps the SDK version to 0.34.0 (including release metadata and changelog) and updates the tracked OpenAPI spec.

Adds a new error_code field to managed auth connection/session types (including SSE state events) to expose machine-readable failure reasons. Updates browser viewport documentation/types to indicate arbitrary dimensions are accepted (with known-good presets) and fixes client request body handling so object bodies can be encoded as application/x-www-form-urlencoded when that content-type is set; also includes minor typing casts in JSON parsing paths.
