Fixes issue 3: the host-agent console showed OCR results but never real UI-tree data, because _ui_tree_nodes() checked for a get_ui_tree/ui_tree tool action that has never existed anywhere in the codebase. - storage/timeline.py: add a ui_tree_results field to TimelineRecord and Timeline.append(), mirroring the existing ocr_results field. - runtime/task.py: _append_timeline() now extracts scene.elements with source == "ui" into ui_tree_results (scene_builder.build_scene() already preserved these; they were just never persisted). - host_agent/web/app.py: _ui_tree_nodes() reads the new field directly instead of the dead tool-action check. New _overlay_payload() exposes each step's scene dimensions and fused element list for client-side rendering. - task_detail.html: adds a toggle to overlay OCR (orange) and UI-tree (blue) bounding boxes on the before-action screenshot, plus a visual marker for the actually executed action (tap circle, or an animated swipe path) using an SVG viewBox so no manual coordinate-scaling JS is needed. Legacy/incomplete records degrade to no overlay, never an error. Also corrects openspec/specs/runtime-task-evidence and host-agent-console-task-pages, which had encoded the same nonexistent-tool assumption, via the new host-agent-console-visual-evidence change. 600 tests passing; ruff/compileall/openspec validate all clean.
