Conversation
This PR adds an `enableTruncation` option to the LangChain integration that allows users to disable input message truncation. It defaults to `true` to preserve existing behavior. Also fixes missing truncation for LLM string prompts in extractLLMRequestAttributes and refactors to use the shared getTruncatedJsonString/getJsonString utilities. Closes: #20138
