feat(sysinfo): Add diagnostic information enhancements (#2880)

Enhanced the PlatformSpecification struct with additional diagnostic information including:
- Added Verge version information to diagnostic output
- Added running mode information (Service/Sidecar/Not Running)
- Improved Debug implementation to display all diagnostic fields
- Implemented asynchronous detection of core running mode

This change helps users provide more complete system information when reporting issues.
