Dependabot upgraded vitest to 4.0.17 but left @vitest/coverage-v8 and @vitest/ui at 2.1.x, causing runtime errors during coverage collection:

TypeError: Cannot read properties of undefined (reading 'fetchCache')
 ❯ V8CoverageProvider.convertCoverage

Changes

  • Upgrade @vitest/coverage-v8: ^2.1.8^4.0.17
  • Upgrade @vitest/ui: ^2.1.8^4.0.17

Vitest requires all companion packages to be on the same major version.
