Atrium v1.0.0

• Initial release: hold ⌥ and tap Tab to switch between windows — every window of every app, minimized and hidden ones included, on whichever screen your cursor is.
• Live window previews on every card, streaming in as they capture; off-screen windows (minimized, hidden, other Spaces) are pictured from the window server's retained backing store, and previews persist across relaunches.
• ⌥ scopes the switcher to the frontmost app's own windows, like the system's ⌘ but with the full panel.
• Cycle with Tab (hold to repeat, ⇧ for backwards), move with the arrow keys, hover or click with the mouse, commit with Return or by releasing ⌥, cancel with Escape.
• A clear Liquid Glass panel that adapts to light and dark mode, in the Domus family's visual language.
• First-run onboarding gates on the Accessibility permission (Screen Recording optional, for previews), and Sparkle keeps the app up to date.
