46-47: Vitest and related packages updated consistently in patch version bump.

The three related packages (vitest, @vitest/coverage-v8, and @vitest/ui) are updated together from 4.0.13 to 4.0.15. This is the correct approach for keeping companion packages in sync, and the patch-level bump (4.0.x → 4.0.y) typically carries low breaking-change risk.

Please verify the following before merging:

1. Run the full test suite to ensure the updated versions work correctly with your test setup:

   pnpm test
   

2. Check the vitest changelog for versions 4.0.14 and 4.0.15 to confirm there are no unexpected breaking changes or behavioral shifts that might affect your test results. Since my knowledge cutoff is March 2025 and this PR was created in December 2025, I cannot confirm the contents of these patch releases.
