Introduce crash monitoring and an OOBE onboarding flow. Adds a crash logger (koring-crash.log), crash-monitor handler/window, preload-crash bridge, crash UI (crash.html, src/crash.tsx, pages/crash) and a debug page. Main process now sets up crash listeners, startup checks (first-launch, .minecraft), and a config reset/factory-reset that removes Koring.yml, koring-auth.json and background cache and can relaunch the app. Exposes config preloading to renderer, adds OOBE pages/layout, confirm dialog store/UI, trims Silk renderer settings, bumps version to 1.0.1 and adds motion dependency, and registers crash.html in Vite. Various related type and config updates included.
