fix(ci): vendor prebuilt Assets.car for the macOS adaptive icon

GitHub macOS runners ship an older Xcode whose actool can't compile the macOS 26 .icon format, so in-CI actool produced no Assets.car and the inject step failed. Compile it locally (Xcode 26) and vendor src-tauri/macos/Assets.car; the script now prefers the prebuilt file, falling back to actool only when absent. Also use local 'npx tauri' for the updater re-sign.
