[counterintuitive] Large context windows eliminate the need for RAG or chunking

Continue using RAG and targeted retrieval even with large context models; only pass the necessary context to minimize cost, latency, and retrieval degradation.

Journey Context:
With 100k\+ context windows, developers dump entire codebases into the prompt. This drastically increases compute cost and latency. More importantly, LLMs still struggle to reliably extract information from the middle of massive contexts. RAG remains essential for identifying the needle in the haystack, then feeding only the needle to the LLM.
