SwiftCUA: reconstructing a macOS computer-use service

SwiftCUA reconstructs the behavior of a macOS computer-use service in Swift 6 after studying the Codex Computer Use.app bundle, its local IPC, permissions and input engine. It provides a background service, CLI, JavaScript bridge and MCP servers for accessibility inspection, screenshots and input, with separate research reports on the original.
