…tual files Addresses an issue where user-defined `coverageInclude` patterns in Vitest could incorrectly exclude bundled virtual files during the pre-sourcemap coverage check, leading to incomplete or empty coverage reports. This change modifies the `generateCoverageOption` function to augment user-provided `coverageInclude` arrays with specific globs (`spec-*.js`, `chunk-*.js`) that match the internal bundled test entry points and code chunks. This ensures that all necessary files are considered during Vitest's initial coverage pass, while still respecting the user's original `include` patterns for the post-sourcemap remapping.
