Anthropic SDK v0.106.0

v0.106.0, released 2026-06-05, marks Claude Opus 4.1 as deprecated and fixes Foundry client `copy()`/`with_options()` behavior plus schema handling so `$defs` are preserved when the root is a `$ref`. That matters because it signals a model lifecycle change while also tightening client and schema tooling used for integrations and code generation.
