Nutritional Balance

Port recipe scan efficiencies from 1.21: Replace per-item recipe scans with a lazy bulk index. Eliminates long hangs on first login in very large modpacks. Pre-resolve all food nutrients on ServerStartedEvent and ship the entire cache to clients in one bulk packet on join (and after /reload), so JEI/REI/EMI tooltip indexing no longer triggers a flood of per-item sync requests. Adds cycle detection and client-side packet de-duplication for safety; bumps the network protocol version to 2.4.

Adjust recipe recursion algorithm to search more deeply and not cache results for non-food items when reached near the end of the recursion budget.
