release 1.3.2: anchor primer WebView in hidden window for reliable startup fetch

Browse Source 
Every launch now loads claude.ai in a real (off-screen, invisible) NSWindow so
WebKit doesn't throttle JS execution. The nav delegate fires adoptPrimerWebView
once the page loads, replacing the old 1.5 s sleep-then-refresh approach.
