Instead of rendering a reference HTML page that wraps an <img> tag pointing to a PNG, Screenshot tests now load the expected PNG directly from disk and compare it against the rendered screenshot. This eliminates the indirection of loading and rendering a second page just to display a static image. This also means --rebaseline now works for Screenshot tests, generating the expected PNG automatically instead of requiring manual screenshot capture and placement. Changes: - Add TestMode::Screenshot with its own collector and runner - Move PNGs from Screenshot/images/ to Screenshot/expected/ with normalized names matching input filenames - Remove all 92 reference HTML wrapper files and the images/ directory - Remove <link rel="match"> from all 94 Screenshot input HTML files - Update add_libweb_test.py Screenshot boilerplate accordingly - Add Screenshot mode to results viewer image comparison tabs
