Create macOS DMG Installer

To support macOS users and provide a native installation experience, we need to build a .dmg installer for the WarpNet node. This will allow users to install and launch the application using standard macOS conventions, without requiring Homebrew, manual builds, or terminal usage.

Tasks:

1. Build macOS binary:

   • Cross-compile or build natively for darwin/amd64 and darwin/arm64 (Apple Silicon).
   • Optionally sign the binary with a developer certificate (for Gatekeeper support).
   • Optional: notarize the binary for distribution outside the App Store.

2. Create .app bundle:

   • Wrap the binary in a standard macOS .app structure (e.g. WarpNet.app),
   • Include Info.plist, icon, and any assets (e.g. logo, config templates),
   • Use tools like create-dmg or dmgbuild to generate the final image.

3. Generate .dmg image:

   • Create a user-friendly drag-and-drop interface (WarpNet.app → /Applications),
   • Optionally include a README or setup instructions inside the DMG.

4. Test and validate:

   • Ensure the app runs on both Intel and Apple Silicon Macs,
   • Ensure permissions (network access, file access) are correctly set,
   • Check for quarantine flags and Gatekeeper compatibility.

Example tools:

• [create-dmg](https://github.com/create-dmg/create-dmg) (Bash-based, simple)
• dmgbuild (Python-based, highly customizable)
• appify or manual .app folder structure

Looking for contributors with experience in macOS packaging or notarization workflows.
