Note

Release 0.25.0 with API additions and breaking auth changes.

• Proxies: New POST /proxies/{id}/check with ProxyCheckResponse
• Credentials: Support id_or_name on retrieve/update/delete; add sso_provider and totp_secret fields; new GET /credentials/{id_or_name}/totp-code; Credential includes TOTP/SSO metadata
• Auth agents: domain (+ optional allowed_domains) replaces target_domain; removed reauth endpoint
• Auth invocations: Removed discover; exchange unchanged; submit now accepts either field_values or sso_button; enriched AgentAuthInvocationResponse (status, step, domain, pending fields/SSO); AuthAgentInvocationCreateResponse always returns invocation_id with type; simplified AgentAuthSubmitResponse
• Client/runtime: Async PATCH now uses async_to_httpx_files; lint script adds --fix; version bump and docs/tests updated
