Licence entry in settings and CIO cable labels

Pro

• Enter your licence key from Settings. The Pro section in Settings now has an "Enter Licence Key..." button that opens the licence window. No more hunting through the right-click menu.

OSS

• CIO cable capability shown for passive and Thunderbolt cables. Ports with a passive or Thunderbolt cable now surface the CIO transport data (cable generation, speed, link width) in the UI, not just in JSON output.
• Pro upgrade links in settings and licence screen. Free users see a direct link to the Pro purchase page from both the Settings panel and the licence window.

Internal

• Windows CI workflow. Cross-platform Swift build now runs on Windows (non-blocking while a Swift 6.0.3 toolchain issue is resolved).
• Pro boundary check in CI. Automated check ensures Pro-only code stays inside the plugins module.
• Ad-hoc signing fix. The CLI helper binary is now signed in the ad-hoc path, fixing codesign --verify --deep failures in local smoke tests.
