Add a starry sky background to the star map, including the new star systems added by Metal and Stars and Dea Dia System.

A full-screen starry sky background has been added. If you don't like it, you can turn it off in the settings.

You can now add asteroid belts inside or outside the star system (freely configurable).

You can also turn off the galaxy background image through settings, displaying only a full‑screen starry background. You can also decide whether the stars twinkle as the perspective moves. (Both are enabled by default.)

If you have any ideas, suggestions, or encounter any problems, please feel free to contact me.

In the graphics settings, atlas texture size needs to be set to 8192 or "largest possible" please.

I learned how to modify the black background of the interface from Powerscooter's Nautical map mod. Thank you very much!
If you want to experience the style of a nautical explorer, you will love this mod.

Added Portuguese (pt-BR) locale. (Thanks to Slondo!)
Added Polish (pl) locale. (Thanks to Hacai!)
