Added a one-click Mod installation feature

● In the main menu scene, clicking the "Workshop" button will open a brand new Mod browser, allowing you to install, delete, and update Mods with one click. No more tedious manual installation as before.

● Fixed a critical bug where the game's frame rate would plummet after installing BepInEx. Players who have manually installed Mods should notice a significant drop in frame rates, but this fix will cause the Map Tweaks Mod to stop working.

● Fixed the bug where sound effects and weather volume would automatically reset to 100%.

Merchant System Progress:
①. Added a standing hoverboard that can be purchased early in the game.
②. Added a railway system, allowing players to lay tracks and quickly travel to designated locations.
③. Added drone propellers that can be installed on vehicles – now vehicles can fly! Added nuclear fission batteries to allow extended flight time.
④. Each biome now has its own unique merchant model, complete with exclusive background music. The items sold by merchants vary by biome.

Currently, there is still a lot of work to be done, such as balancing adjustments, bug testing, and more. Therefore, it will take some more time. We sincerely apologize for the long wait.
