This adds a new 'headless' option to the unit-test builder. When set to true, it forces all configured browsers to run in headless mode. This option allows users to force headless execution in non-CI environments (where it is already the default) or to explicitly control the mode regardless of the browser name. Informational messages are now logged when the option is redundant (e.g., all browsers are already headless), ignored (e.g., using the preview provider), or irrelevant (e.g., no browsers configured). The 'karma' runner does not support this option and will log a warning if it is used.
