Updated addon.json to match the current workshop tags and title, as well as ignore GitHub files.

The skybox has been changed from pure magenta to a more theme-accurate pink.

Adjusted the volume of sunstorm sound effects.

Fixed bug causing the main sunstorm ambience to be completely replaced by distant void thunder rumbling in random sessions. This thunder is no longer tied to StormFox ambience and will instead play when sunstorm blasts are on cooldown, serving as an audio cue that a storm is active (useful for random weather) whenever the player would otherwise be too deep underground to hear it.

Fixed sunstorm blasts damaging players when weather damage is turned off.
