Add more controls for full-screen deployment

[vecnode]

Addressed by #12, which added two fullscreen controls to the side panel: Full Window (fills the app's content area) and Fullscreen (drives the native OS window borderless full-screen via the window.neoSetDesktopFullscreen JS→C++ bridge, so the sketch covers the whole desktop; Esc restores the window). Closing as done — happy to open a focused follow-up if you want additional deployment controls (e.g. monitor selection, hide-cursor, kiosk/auto-start).
