FSit Continued

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): FSitMod did not start: java.lang.NoClassDefFoundError: net/minecraft/core/HolderSet; FSitModClient did not start: java.lang.NoClassDefFoundError: net/minecraft/core/HolderSet.
