ZCode Account Switcher 1.0.1

Changes:

• Added Sparkle update checking using the public appcast.
• Improved import feedback so failed imports show the first actionable reason.
• Added an import/export round-trip test.
• Fixed DMG packaging when another volume with the same name is already mounted.

Install:

1. Download the DMG.
2. Drag the app to Applications.
3. If macOS blocks this unsigned build and you trust this release, run the included quarantine helper or run:

xattr -dr com.apple.quarantine "/Applications/ZCode Account Switcher.app"
open "/Applications/ZCode Account Switcher.app"
