# 装 pi-launcher.app 到 /Applications/,并强制刷新 macOS 图标。
#
# 背景: macOS LaunchServices 会把 com.wails.pi-launcher 的图标缓存成
# 当前 app 文件的快照。每次 wails build 之后 .app 内容重建,缓存可能不刷新,
# 导致 Dock 显示默认 .app 占位图而不是真实 icns。
#
# 解决: 把 .app 复制到一个稳定路径(/Applications/),重建时先 rm 再 cp,
# lsregister -f 强制重新注册。
#
# 用法: ./scripts/install-app.sh
