AiGateway uses getenv(LITELLM_MASTER_KEY) + stream_context HTTP which was failing on the chloe virtualhost process. New dbnToolsLiteLLMEmbedBatch() helper mirrors dbnToolsCallGpuLlm — hardcoded URL + key, cURL-first, same pattern already proven for LLM calls. Removes AiGateway dependency from DeepResearchAgent entirely. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
