Posted a review on PR #31016.

Summary: Clean docs update — no issues found.

What changes: Adds documentation for the devOnly option (a boolean | (() => boolean)) to both the PluginConfig and AuxiliaryWorkerConfig sections of the Vite plugin API reference page. The option excludes a Worker from the production build when set to true, with special handling for entry Workers that writes an assets-only Wrangler config for static deployment.

Labels already applied: product:workers, size/s — appropriate for this change. Appropriate labels: documentation, size/s. The PR could also benefit from a documentation label.

No critical issues, high issues, or style guide violations detected. The PR follows existing page conventions, uses correct component syntax (Type, MetaInfo), and the prose is clear and consistent with the rest of the API reference. No changelog entry is needed for this docs-only addition.
