Fix release ZIP: use robocopy staging to preserve SuaviUI/ root folder

The old Compress-Archive -Path approach flattened the directory structure,
placing all files at the top level instead of inside SuaviUI/. Switched to
robocopy staging which preserves the folder hierarchy. Also added .claude,
.busted, spec/, mocks/ to exclusion list.

+**IMPORTANT**: Do NOT use `Compress-Archive -Path $files.FullName` — it flattens the
+directory structure, losing the `SuaviUI/` root folder and duplicating files at the
+top level. Use robocopy staging instead:

 ```powershell
 cd "e:\Games\World of Warcraft\_retail_\Interface\AddOns"
