Root package incorrectly marked as dev in lockfile

Medium Severity

The lockfile regeneration added "dev": true both at the top level of package-lock.json (line 6) and on the root package entry "" (line 11). This was not present before this PR. The root package @cypress/code-coverage has production dependencies (like chalk, dayjs, nyc, etc.) that consumers rely on. Marking the root as a dev package could cause npm ci --omit=dev or production installs to incorrectly skip production dependencies. This appears to be a Renovate lockfile regeneration artifact likely triggered by the self-referencing "file:." entry in devDependencies.
