📄 Description

Description

Adds a dedicated distributed tracing section to the A2A endpoint docs, covering how contextId maps to thread_id in LangSmith, how to propagate thread_id across multiple agents for unified trace grouping, and how to instrument non-LangGraph agents (e.g. Google ADK) using OpenTelemetry. Also adds a description frontmatter field for SEO.

Fixes DOC-576
