[frontier] Agent misreads UI text causing wrong actions in screenshot workflows

Implement dual-path text verification: use VLM OCR confidence scores, then cross-validate with DOM textContent extraction when confidence < 0.95 or for critical actions.

Journey Context:
VLMs silently hallucinate text in images, especially small fonts \(<12px\), low-contrast colors, or overlaid elements. Standard OCR \(Tesseract/EasyOCR\) fails on stylized UI but catches what VLMs miss. For web agents, the DOM provides ground truth but is unavailable for desktop apps. The robust pattern uses VLM for spatial reasoning and layout, then validates text content through secondary OCR or accessibility APIs before executing critical actions like 'delete' or 'transfer'.
