Anthropic SDK v0.98.0

Version 0.98.0 adds improved Managed Agents APIs, client support for Workload Identity Federation, interactive OAuth, and auth profiles, plus the ability to set headers via environment variables. It also fixes streaming stop_details propagation, multipart file array field naming, and missing us/eu multi-region base_url branches in the Vertex async client, which should reduce auth and integration issues.
