Update postcss-modules to v9 (a9539d6)
Vite now depends on postcss-modules v9 and carries a new patch for its typings, keeping the package compatible with the upgraded release. This is a meaningful dependency update because it affects Vite’s CSS modules pipeline and the surrounding type surface.
Other misc changes
- Docs: delegated the virtual modules convention explanation to Rolldown docs and simplified the local guidance.
- CI: switched the ecosystem CI trigger workflow to read the GitHub App client ID from
varsinstead ofsecrets.
