[frontier] Reactive RAG retrieval adds 500ms\+ latency to every agent turn

Use MCP Resource templates to prefetch likely-needed context before the agent asks; implement speculative context loading based on conversation trajectory

Journey Context:
Waiting for retrieval breaks flow and adds round-trip latency; speculative prefetching uses MCP Resource templates \(e.g., \`file:///\{path\}\`\) to load likely resources into working memory before the agent requests them; agent confirms usage rather than waiting for fetch; requires predictive heuristics \(what did user ask about last time?\) or explicit intent signals; reduces perceived latency to zero for cache hits; requires careful cache invalidation via Resource subscriptions
