LangChain Anthropic integration adds skills support and SDK 1.0

You can now pass a top-level skills parameter via container, use an updated thinking display mode, and rely on the integration supporting the Anthropic 1.0 SDK, with gateway response metadata now surfaced and the advisor-tool-2026-03-01 beta header auto-appended for the advisor_20260301 tool. This is a non-breaking update, so no code changes are required to adopt these additions.

Matters for: Teams building agentic applications with Anthropic's tool-use and skills features through LangChain.
