fix(wrapper): track real window geometry on headed launches

Browse Source 
Headed launches applied a fixed emulated viewport on top of the real
browser window, yielding outerWidth < innerWidth (an impossible window).
Default headed new_page()/new_context() to no_viewport so the page tracks
the real window; headless keeps a deterministic viewport. Covers Python
launch/launch_context/launch_persistent_context (+async) and the JS
Playwright/Puppeteer wrappers. Explicit viewport still honored.
