Note

Medium Risk
Medium risk because it changes public SDK surface area (new projects.list(query=...) parameter and expanded MFA option type literals) which could impact downstream type checking and behavior if consumers rely on exhaustive unions.

Overview
Bumps the SDK to v0.53.0 (version metadata, changelog, and updated OpenAPI spec pointers).

Adds server-side search support to projects.list() via a new optional query parameter (sync + async) and updates the corresponding params type and tests.

Extends managed auth models to recognize a new MFA option type/linked_mfa_type value "switch", updates various resource/type docstrings to state name uniqueness is scoped to the project (not org), and fixes an internal file-upload TypeError message to use an f-string.
