This is a minor version upgrade for vitest and its coverage provider @vitest/coverage-v8 from v4.0.18 to v4.1.8.

Key Changes:

• Vite 8 Support: This version introduces support for Vite 8. [2]
• Potential Breaking Change in test.extend: The test.extend API has a new builder pattern. Previously, it passed an undocumented Suite object as the first argument to the factory function; this is no longer the case. While the vitest team believes the usage was minimal, this is a behavioral change that could break tests relying on that argument. [2]
• Coverage Ignore Hints: For @vitest/coverage-v8, this version re-introduces support for /* v8 ignore start/stop */ comments to exclude code from coverage reports, a feature that was present in v3 but missing in v4.0. [2]

Recommendation:
The risk is assessed as medium due to the behavioral change in test.extend. Developers using this API should verify their tests after the upgrade. No other significant breaking changes are documented for this specific version jump.
