Fast Crafting Grid

Fast Crafting Grid reduces crafting UI lag on heavily modded Vintage Story servers.

Inspired by other crafting optimization mods and when I got annoyed by UI freezing.

• replaces the crafting grid's recipe lookup with a much faster indexed matcher designed for large modpacks.
• caches repeated grid states and adds lightweight prefilters for expensive recipe checks that can be triggered during inventory and UI updates.
  
  

In testing, the prefilter rejected over 99% of high-volume recipe checks from the client UI path, including handbook conflict scans triggered by crafting grid updates.

No gameplay changes. No recipe changes. Just less waiting for the crafting grid to figure out what you're making.
