[frontier] Agents interact with skeleton UI placeholders before content stabilizes

Implement pixel-diff stability check: wait until region changes <2% over 500ms before clicking

Journey Context:
Fixed sleeps are either too slow \(hurting latency\) or too fast \(hitting moving targets\). DOM observers miss canvas/WebGL content. Pixel-diffing the specific region of interest catches visual stability regardless of underlying rendering technology, balancing speed and reliability. This pattern is emerging as the standard in SOTA computer-use implementations, replacing the 'wait for selector' pattern from DOM-based automation.
