Clear and concise description of the problem

I would like to propose an enhancement to Vitest's coverage report system, specifically regarding the use of the LCOV reporter. Currently, the Vitest UI only recognizes the HTML reporter for displaying coverage results, which generates files directly in the root of the /coverage folder. This approach can lead to clutter and makes it harder to manage and share the reports, especially in CI/CD environments.

I suggest that Vitest should also support the LCOV reporter in its UI. The LCOV reporter creates the same HTML files but places them inside a dedicated lcov-report directory within the /coverage folder. This would result in a cleaner and more organized structure, making it easier to generate and distribute coverage reports without cluttering the root folder.

Supporting both reporter 'lcov' or 'html' would maintain compatibility while enhancing organization and usability.
