* chore: extract `BrowserRunner` into its own module `src/Launcher.ts` is large and hard to work in. It has multiple objects defined in it: * ChromeLauncher * FirefoxLauncher * BrowserRunner * Launcher This change moves BrowserRunner into its own module. More refactorings like this will follow but this is the first step.
