[frontier] RAG retrieval happens too late causing agent to backtrack when hitting knowledge gaps

Use trajectory prediction to pre-fetch \(hydrate\) context the agent will likely need in 2-3 steps based on current reasoning trace, not just immediate query.

Journey Context:
Naive RAG retrieves based on immediate query, but agents often need multi-hop reasoning. When the agent realizes it needs related facts mid-trajectory, it must backtrack or stall for retrieval. Frontier systems use the LLM's own reasoning trace to predict upcoming information needs—speculatively hydrating context windows with likely-to-be-needed documents before the agent asks. This turns RAG from reactive to predictive, reducing latency and reasoning errors by treating context as a pre-fetched working set.
