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>

<!-- This testcase checks that flex items are painted as pseudo-stacking
|
|
contexts, instead of full stacking contexts. In other words, content
|
|
inside of one flex item should be able to iterleave between pieces of
|
|
content in another flex item, if we set appropriately interleaving
|
|
"z-index" values. -->
