Replace the standard QMainWindow chrome and QTableWidget with a purpose-built Qt UI built around hand-rolled widgets and animations: - SplashScreen: frameless translucent splash with a wordmark fade/scale, a sweeping scan line and a pulsing accent glow. ~950ms total cold-start reveal that fades out into the main window. - TitleBar: custom title bar replaces the OS frame, owns drag-to-move, minimize/close buttons, and a breathing scan-status dot. - InstanceList + InstanceRow: scrollable column of self-painted rows (PID, title, Inject button). Rows are not selectable, double-click has no special meaning - injection happens only through the button. Hover animates each row's tint; new pids play a slide-in/opacity entrance. - InjectionOverlay: modal-style frameless overlay shown while inject() runs in a worker thread. Spinner ring + progress bar advance during injection; completion swaps to a checkmark / X, holds briefly, then fades out. After it closes, the main window fades and the loader self-quits. - MainWindow: frameless + translucent panel painted by hand; entrance fade/slide on launch; uniform playExitThenQuit() shared by the close button and the post-injection path so every exit path gets a fade-out instead of a hard vanish. Also enables Win11 rounded corners via DwmSetWindowAttribute on show. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
