Cleanup codebase and update to 26.1

[misode]

🫡😢 Discontinued modules

We decided to discontinue some modules with this update. This is necessary to keep the project maintainable and allows us to add new modules without growing endlessly. They are listed here along with some of our reasoning:

• Better Fire
• Custom Crafters (library)
  • Almost fully replaced by vanilla recipes (see feature changes for exceptions)
• Enchantment Extractors
  • It is able to separate good enchantments and curses
  • Doesn't work for custom enchantments
• Enderman Support Class
• Forming Press
  • A worse crafting table (not much initial cost) that gives access to more efficient recipes
• Heart Canisters
  • This is a boring implementation of extra hearts
• Mob Curing
  • Feels random
• Mountaineering
  • Very niche use case, not intuitive to use
• Poses Pack
  • Hardcoded poses aren't necessary now that poses can be fully customized
• Potion Swords
  • Mainly used to get wither skulls, which is OP. The rest of the module is unused
• Relocators
  • Not really used except for liquid tanks
• XP Storage
  • Does the same as liquid tanks but with no cost

✨ Feature changes

• With the removal of custom crafters, you can no longer craft boots of ostara from existing leather boots

🚧 TODO

• Remove overlays
• Discontinue modules
• Replace guidebook gm4_recipes with vanilla recipes
• Update video's with crafting tables (standard crafting)
• Re-implement guidebook recipes with atlas text component type
• Change custom_name components into item_name
• Change how custom model data is done
• Finish this to-do list
