Add scripts/import_wpt_reftests.py to sparse-clone the upstream WPT repo and bulk-import qualifying CSS reftests (no JS, no external resources) as known_fail entries. 23 tests already pass and are promoted. The import script is idempotent and exposed via `just import-wpt`. CI now prints the WPT summary (pass=36 known_fail=2877 skip=1) on every run. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

<meta content="The margin area of an element is always transparent. The background-color of an element never paints its own margin area. The background-color of an element only paints its own border area (if any), its own padding area (if any) and its own content area (if any). Therefore the background-color of the content area (and of the padding area, if any, and of the border area, if any) of a parent element shines through the margin area of its child. In this test, div#parent is painted green and is 100px by 100px; its sole child has an 99px margin bottom and a 100px margin right margin which are transparent and through which we can see the background color of its parent." name="assert" >
