Fixed

• Black screenshots on external displays: capturing an area, window, or fullscreen on a secondary monitor no longer produces an empty black image. The capture engine matched displays by comparing rectangles from two different coordinate systems, which only agree on the primary display; displays are now matched by their display ID. The same fix applies to screen recordings, scrolling capture, OCR/barcode capture, and the frozen selection preview.
