Pull request overview

This PR implements the feature requested in Issue #111 to automatically open the site URL in the user's default browser when a site is brought up via mchef. It adds OS detection helpers, a cross-platform browser-open method in CliService, and integrates it into both the Main::up() flow and the Up command.

Changes:

• Added isMac() and isLinux() static methods to the OS helper class for cross-platform OS detection.
• Added openSite() method to CliService that opens a URL in the default browser, with CI mode detection and OS-specific command selection.
• Integrated openSite() into both Main::up() and the Up command's execute() method to open the Moodle site after containers start.

On Windows, the start command interprets the first quoted argument as a window title, not a URL. If you add escapeshellarg() around $url (as recommended for security), start will treat the quoted URL as a window title and fail to open the browser. The conventional fix is to use start "" <url> to provide an empty title first. Even without escaping, this is a good practice to handle URLs that might contain spaces.
