Sky Recomp v2.0.1: Bug fixes and performance improvements

This update addresses cutscene display scaling, in-game language settings, and long-session performance on Linux.

Fixes and improvements

• Dynamic resolution scaling in cutscenes: Fixed an issue where heavy scenes with dynamic scaling (such as the tornado sequence) would shrink into the bottom-left corner with black borders. The viewport now scales to fill the display.
• Language selection and restart prompt: Added language options to the launcher settings and the Video menu. Changing the language in-game now prompts to restart immediately or keep the change for the next launch, making it clear that text archives reload on boot.
• Texture pack handling: Folders in the textures directory are no longer indexed as game data mods, preventing duplicate lookups during file access.
• Linux performance over time: Reworked texture change checks on Linux to use fast sampling before running full hashes on CPU memory. Textures that remain unchanged now drop back to periodic checks, eliminating frame drops during long sessions with custom textures.
