A low-level, self-contained bridge to the macOS native API using purego for direct system calls. A private backend for a higher-level, cross-platform PAL

I released it as a self-contained package because none exist for this purpose without using 'cgo' and I also abstracted joystick functionality which is also unique

The package is structured to provide direct access to the Objective-C runtime and various Core Foundation frameworks without external dependencies

• init.go: Dynamic loading of system frameworks, registers Objective-C classes, and maps selectors for message-passing
• types.go: Go representations of native structs and Objective-C objects
• app.go: Native NSApplication lifecycle and menu bar creation
• window.go: Functions for creating and manipulating native NSWindow and NSOpenGLView objects
• events.go: Wrappers for retrieving data from native NSEvent objects
• callbacks.go: Go functions that receive callbacks from the Objective-C runtime, bridging native events to Go
• thread.go: MainThread function, a critical utility for dispatching code to the main OS thread as required by the AppKit framework
• clipboard.go: Clipboard access using NSPasteboard
• joystick.go: IOKit framework to handle joystick and gamepad input
• memory.go: Objective-C memory management calls (Retain, Release, Autorelease)
• helpers.go: Utility functions for Objective-C message sending and Go pointer management

This package is not intended for direct use by end-user applications
