…n.name LangChain was the odd one out — LangGraph already sets the conventions attribute, while langchain.chain.name was a JS-only key. Unnamed chains skip the attribute rather than writing unknown_chain into a registered key. Fixes#23683 Co-Authored-By: Cursor Grok 4.6 <cursoragent@cursor.com>

m: We don't want to set op anymore directly, I think. Right @Lms24?

LangChain chain spans now emit gen_ai.pipeline.name instead of the js only langchain.chain.name, matching LangGraph so dashboards, alerts, and span-name templates share one key. Unnamed chains omit the attribute rather than writing unknown_chain; span names are unchanged.
Fixes#23683
