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

Continue chunking documents and retrieving top-k segments rather than stuffing entire documents into the context window.

Journey Context:
With 128k\+ context windows, developers skip chunking and pass whole documents. This causes attention dilution \(the model misses instructions\), drastically increases latency and cost, and increases the risk of the model relying on spurious or contradictory information buried in the text.
