driver.tree() failures (WDA/Appium session errors) previously raised uncaught, killing describe_screen() before OCR ever ran. Malformed tree content (invalid XML) had the same problem inside parse_ui_tree(). Both are now caught and logged, falling back to an empty ui_elements list so the scene degrades to OCR-only, mirroring the existing OCR-failure fallback in run_ocr().
