fix(opencv): correct contour type for findContours

Browse Source 
Changed contours from cv.Mat to cv.MatVector to match OpenCV.js API
requirements. The findContours method expects a MatVector for contour
storage, not a single Mat object. This fixes a potential runtime error
when using OpenCV-based panel detection.
