LangChain-Anthropic 1.5.4 fixes tool-calling bugs, adds user profile ID

Full analysis

LangChain released version 1.5.4 of its Anthropic integration package, shipping two bug fixes relevant to agent tool use: one corrects handling of tool schemas that contain unsupported top-level composition (e.g., anyOf/oneOf at the root), and another preserves the caller-supplied tool_choice parameter so agents can reliably control which tool is invoked. A new user_profile_id convenience attribute was also added, likely to support Anthropic's user-level tracking features.
