Zachary D. Rowitsch 16abbd78e7 Bulk-import 2899 WPT CSS reftests and add import tooling
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.

<title>CSS Test: Collapsing margins - margin-bottom of the last in-flow child block collapsing with its max-height parent block's bottom margin</title>

<meta content="The 'max-height' of a parent block element should have no influence over whether such parent block element's bottom margin is adjoining to its last child's bottom margin. In such situation, the bottom margin of the parent block element and the bottom margin of its last child should collapse as long as such parent block element has no bottom padding and has no bottom border." name="assert" >
