macOS Electron App → Linux Converter

This skill guides the conversion of a macOS Electron app (distributed as .dmg) into a native Linux app, including packaging as .deb.

When this skill triggers

• Porting a macOS-only Electron app to Linux
• Building app.asar and native modules for Linux from a macOS DMG
• Patching Linux window behavior (icon, menu bar, background color)
• Fixing post-conversion startup crashes (product-name missing, t.join is not a function, flickering)
• Packaging the result as .deb, .rpm, or running directly from a folder
