… Vitest runner This commit fixes an issue in the Vitest browser setup where headless mode was not correctly configured on a per-browser-instance basis. Previously, the headless mode was applied globally, leading to incorrect behavior when mixing headed and headless browser names, or in specific environments. Now, the configuration correctly: - Determines headless status from individual browser names (e.g., `ChromeHeadless` vs `Chrome`). - Forces all instances to be headless in CI environments. - Ensures the Preview provider forces instances to be headed. - Enables the UI only when running locally with at least one headed browser.
