x3utils CLI v1.8.0

This release brings the Windows, Linux, and macOS CLI tools back to the same version and gives all three platforms a consistent launcher workflow.

What’s new

• Added a read-only Check Connection action for modes A/B/C/D.
• Reordered the launcher actions to match the Flutter GUI workflow.
• Added an Advanced submenu with:
  • Flash Only
  • Flash Slot 0
  • Check Protection
  • Unlock / Rescue
• Protection actions honor the connection mode selected in the launcher, including Power-race.
• Preserved standalone script usage, Windows drag-and-drop, and Bash file prompts.

macOS improvements

• Completed Power-race support across dump, flash, SHU-compatible flash, Flash Only, and Slot 0.
• Added architecture-aware Power-race target configurations for bundled xPack OpenOCD.
• Added evidence-based Mode-D protection checking and rescue.
• Improved handling of xPack OpenOCD’s slower and slightly different output.

Safety

• Check Connection does not dump or write firmware.
• Normal flashing still requires a successful backup first.
• Flash Only remains under Advanced because it deliberately skips the backup.
• Unlock / Rescue retains its explicit UNLOCK confirmation and can mass-erase main flash.
• A blank chip left after rescue is rejected by Backup + Flash and can be restored with Advanced → Flash Only.

Validation

Connection checking passed on real hardware in modes A/B/C/D on Windows, Linux, and macOS.

Integrated launcher backup, SHU-compatible flashing, normal flashing, Flash Only, Slot 0, and protection workflows were exercised across the supported platforms. macOS Power-race rescue was also destructively validated, followed by successful blank-chip detection and firmware recovery.

The Flutter GUI remains separately versioned and is unchanged by this CLI release.
