When a second display is connected (macOS), presenting now opens a borderless audience window on the beamer showing the slide, while the main window shows the presenter view (current/next slide, speaker notes, clock, controls) on the laptop. The two windows stay in sync over method channels: navigation, blank screen, audio-complete and beamer clicks are forwarded between them, and media plays only on the beamer to avoid double audio. Falls back to the existing single-window presenter when there is one display or the second window can't be created. - Vendors a fork of desktop_multi_window in third_party/ that re-adds the native macOS window geometry/fullscreen calls (coverScreen, setFrame, close) the published 0.3.0 dropped; wired via a path dependency. - Registers the app's plugins for sub-windows in MainFlutterWindow so video/image rendering works on the beamer. - Routes the multi_window dart entrypoint to a minimal AudienceWindowApp. Compiles (flutter analyze + macOS debug build) and all tests pass; runtime two-screen behaviour still needs verification on real hardware.
