v0.47.0 — the mouse-click display fixed

Fixed

• A mouse click no longer shifts the display by one row, and no longer re-draws the prompt. Clicking the session log (a plain press-and-release on a log row) used to end the mouse pass by repainting the pinned prompt block from scratch — the same tail path a wheel notch or a drag takes. A click that changes nothing now changes nothing on screen: the press records the drag's anchor without painting, the release repaints only when the gesture actually put the scrolled screen up (a real drag, or a wheel notch), and an empty gesture no longer spawns the clipboard copy command. Wheel scrolling, drag-select-and-copy ([clip] report included) and the thinking view's click-toggle are unchanged.
