WIP: add Electron platform configuration to Capacitor

- Add electron platform section to capacitor.config.json
- Configure deep linking with timesafari:// scheme
- Set up build options for macOS, Windows, and Linux
- Configure output directory and file inclusion
- Add platform-specific build targets (DMG, NSIS, AppImage)
- Support both x64 and arm64 architectures for macOS
- Set appropriate app categories for each platform

This enables building TimeSafari as a native desktop application
using Capacitor's Electron platform while maintaining existing
mobile and web functionality.
