[frontier] Agent stalls when switching between vision analysis and text generation mid-task

Pre-allocate vision tokens and batch all visual queries into single observation rounds before text generation phases; avoid alternating modalities turn-by-turn

Journey Context:
Current agents treat vision and text as symmetric modalities, but transformers incur significant KV-cache recomputation and attention-mask fragmentation when switching between image and text token spaces. The common mistake is submitting a screenshot, getting text analysis, then submitting another screenshot immediately. This causes latency spikes and attention drift. Instead, agents should 'speculatively' gather all visual evidence in a single batch \(visual snapshotting\), then enter extended text-reasoning phases. This trades immediate interactivity for throughput and coherence, similar to how database transactions batch reads before writes.
