* fix: host browser popups in an Orca origin-bar window instead of chrome-less child windows A guest-opened popup previously became a default Electron child window with no address bar, so users could not verify a popup's origin — a phishing surface flagged in the prod-release scan of #7392. The reverted #8332 tried gating on disposition, which is bypassable and breaks featureless window.open() OAuth flows. Instead, keep hosting popups in-app (preserving the shared session partition and live window.opener handle OAuth depends on) but build the child window ourselves via setWindowOpenHandler's createWindow callback: a BaseWindow with an Orca-controlled origin-bar WebContentsView on top and a content WebContentsView that adopts the pre-created popup WebContents. The bar shows only the destination origin (never path or query), updates on navigation, and flags plain http to remote hosts. Also pins secure webPreferences (contextIsolation, no nodeIntegration, sandbox, no webviewTag) on popup children via SAFE_POPUP_WINDOW_OPTIONS, attaches guest policies to popup contents directly (did-create-window does not fire for createWindow children), emits the existing opened-in-orca renderer notice, and closes popups with their opener guest.

Match Chrome popup behavior: title bar shows the page title (reset to origin on navigation so a stale title cannot outlive its origin); the origin bar below remains the unspoofable trust surface. Co-authored-by: Orca <help@stably.ai> * fix: elide the start of long popup origins so the registrable domain stays visible Adversarial review findings on the origin bar: - The bar right-ellipsized long hostnames, hiding exactly the part that matters: window.open('https://accounts.google.com.<...>.evil.com', '', 'width=360') rendered as 'https://accounts.google.com.signin.s…'. Clip from the left instead (rtl container + isolated ltr bdi so host and port keep normal character order), matching how Chrome elides. - Re-assert the origin on the popup's did-finish-load so a transiently dropped executeJavaScript write cannot leave a stale origin up. - Re-pin view layout on enter/leave-full-screen: verified at runtime that HTML5 fullscreen keeps the bar visible on macOS (resize fires); the explicit events make that hold on every platform. - Test hardening: fake WebContents now flips isDestroyed after 'destroyed' so the double-close guard is actually exercised.
