ultracite@7.12.0

Minor Changes

1f427d7: Add an opt-in ultracite/oxlint/shadcn preset for @shadcn/lint, shadcn’s agent-first linter for Tailwind v4 design systems. All six rules (no-restyle, no-raw-colors, no-arbitrary-values, no-inline-styles, no-unknown-classes, require-static-classes) run at error with the upstream allow: ["layout"] policy, and the component-authoring rules are relaxed inside **/components/ui/**. Enable it with ultracite init --linter oxlint --js-plugins @shadcn/lint, or extend it alongside ultracite/oxlint/core after installing @shadcn/lint.

600e991: Accept file-based page route filenames in github/filenames-match-regex. Files under pages/ (Astro, Next.js pages router) now match a bracket-aware pattern, so dynamic, rest and optional parameters such as [slug].astro, [...slug].ts and [[...slug]].tsx pass while non-route names like BadPage.ts are still rejected.
66f97bb: Allow top-level return in Astro frontmatter. The core preset now turns off unicorn/prefer-module for **/*.astro files (the rule cannot be configured to allow only return), and keeps require(), module.exports, __dirname and __filename flagged there via import/no-commonjs and no-restricted-globals.
