fix(core): restore cloakbrowser + update lockfile with quickjs-emscripten

Reverted the two commits that accidentally removed CloakBrowser support.
CloakBrowser was working correctly — it allows secure.booking.com to be
accessed in headless mode without watch mode workaround.

Also adds quickjs-emscripten to core dependencies (was missing from lockfile,
causing build failures after the reset).
