Fixed EGO-L-004 warning. Main loop sources (GLib.timeout_add) are now properly tracked in an array and removed using GLib.Source.remove() during the extension's disable() phase to prevent memory leaks.

You can also add `donations` to the `metadata.json`, so people can donate to you if they want: [Extension Anatomy: donations](https://gjs.guide/extensions/overview/anatomy.html#donations) If you need any help with your extension you can ask us on: - [GNOME Extensions Matrix Channel](https://matrix.to/#/#extensions:gnome.org) - IRC Bridge: irc://irc.gimpnet.org/shell-extensions

Thank you for the review and the useful links! I’ll keep the donations field in mind for future updates once the extension matures. Thanks for your support!
