Leaving global keyboard shortcut empty by default

[djpowers]

While trying out the app, I realized that HuggingChat was intercepting the ⇧⌘⏎ shortcut set for a common action in another app. While I see that the "Global Keyboard Shortcut" value is customizable in the "General" section of the settings, it's jarring when a shortcut action unexpectedly no longer works.

For some additional context, Sindre Sorhus maintains a popular library for setting user-customizable global keyboard shortcuts, and urges developers not to set default global hotkeys for the same reason: https://github.com/sindresorhus/KeyboardShortcuts?tab=readme-ov-file#default-keyboard-shortcuts

Thanks for considering this suggestion! 🌐
