[frontier] Vision API latency stalling agent reasoning loops in computer-use workflows

Implement speculative visual encoding with lookahead: while executing text reasoning step N, pre-encode predicted screenshots for step N\+1 in a parallel process/thread; cache visual embeddings so that when the agent finishes reasoning, the vision processing is already complete, eliminating API wait time from the critical path.

Journey Context:
Computer-use agents often pause for 1-3 seconds per step waiting for vision API responses \(base64 encoding \+ API latency\). In 50-step tasks, this adds minutes of idle time. Alternatives: local vision models \(quality drop\), batched requests \(couples steps\). Speculative encoding assumes the agent can predict likely next screenshots \(e.g., after clicking 'submit', the next screen is predictable\). Even with 70% prediction accuracy, the speedup is significant due to parallelization. This requires an 'encoder pool' running async to the main agent loop, using predicted action effects to render next states.
