Critical Bug Fix: First-Launch Crash

This release fixes a critical crash that prevented the app from launching on some systems, particularly affecting first-time users on macOS 14.x with Apple Silicon.

What happened?

The app’s theme system (ThemeManager) attempted to access NSApp.appearance during SwiftUI’s initial view render — before macOS had fully initialized the application object. On certain system configurations, this caused an immediate EXC_BREAKPOINT crash roughly 36 milliseconds after launch, before the window could even appear. The issue was most reliably triggered on a clean first launch with no existing preferences.
