Pull request overview

Updates the @scratch/task-herder workspace to use official Vite v8 now that Vite defaults to Rolldown, removing the prior npm alias override to rolldown-vite.

Changes:

• Remove the overrides entry that aliased vite to npm:rolldown-vite@7.3.1.
• Set packages/task-herder devDependency vite to 8.0.8.
• Regenerate package-lock.json to reflect the new Vite/Rolldown dependency graph.
