xvideos renders the scene's models as `<a href="/models/slug">...<span class="name">
Display Name</span>...`. The old _MODEL_RE wanted text immediately after the anchor
`>` and never matched current markup → browse-scraped scenes landed with 0 performers
(bug-report 2026-06-07: "no actors, but Rebecca Johnson is on the page"). New regex
captures slug + nested span.name, bounded within the anchor. + backfill script for the
~11.9k existing zero-performer xvideos scenes (54% have a real /models/ link; resolver
merges names to canonical by name_normalized).
