+- **fix(providers):** strip `<script>`/`<style>` blocks from the Vertex model-docs HTML even when the end tag carries junk before the `>` (`</script foo>`, which the HTML spec still treats as a close). The old regexp required `</script\s*>`, so such a block survived; the generic tag-stripping pass then removed both tags and kept the script BODY, letting its text reach the table cells the context-window/token-limit parser reads (CodeQL `js/bad-tag-filter`, alert #1007).
