Windows Fixes
- UAC admin elevation: exe auto-prompts for admin (required for SCSI passthrough, same as C# app)
- Persistent SCSI transport: keeps DeviceIoControl handle open across frames — no more theme blinking
- SCSI poll timeout: 15s timeout + graceful FBL=100 fallback for USB latency
- Installer process kill: auto-kills running TRCC before file overwrite (no more "file in use" errors)
- Uninstaller cleanup: kills processes + removes autostart entry on uninstall
- tzdata dependency: timezone data for Windows (Linux provides via OS)
Cumulative Windows fixes since v8.6.7
Detection → PhysicalDrive → SCSI passthrough → frame send — full path working on Windows with admin elevation.
