When both LangChain and an AI provider integration (OpenAI, Anthropic, Google GenAI) are active, a single LangChain invoke() call produces duplicate gen_ai.chat spans — one from LangChain's callback handler and one from the underlying provider instrumentation.
The previous fix globally disabled provider instrumentations when LangChain was detected, but this broke direct provider SDK calls unrelated to LangChain.
This PR sets a suppression flag on the current scope during LangChain invoke/stream/batch execution. Provider instrumentations check this flag and skip span creation if set.
Closes #19687
