[frontier] Vision tokens exhaust context window in screenshot verification loops

Implement strict visual token quotas \(max 2k tokens per step\) with forced text serialization of visual state before subsequent reasoning

Journey Context:
OpenAI vision pricing consumes 85-170 tokens per 512x512 tile. Agents recursively screenshot to verify state, consuming 8k\+ tokens per loop until context window overflow causes task abandonment. The naive fix switches to DOM-only after initial visual grounding, but this misses color-coded status and visual semantics. The correct 2025 pattern is 'Visual Token Quotas' - allocate fixed 2k tokens per step, force the agent to output text descriptions of visual state \('red button is disabled'\), then drop the image before the next reasoning step. This maintains visual context without token bloat.
