Replace sandboxed Capacitor filesystem with native IPC for reliable file exports: - Add IPC handler in main process for direct Downloads folder access - Expose secure electronAPI via contextBridge in preload script - Update ElectronPlatformService to use native IPC with web fallback - Add TypeScript definitions for electron APIs - Fix file export issues where files were trapped in virtual filesystem - Enable proper date-stamped backup filenames in Downloads folder - Follow Electron security best practices with process isolation Files now export directly to ~/Downloads with exact path feedback.
