Frostbyte's Maximum Mobility

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

Evidence

Ran on Kiln's test stand (2026-11-04): 1140 ticks with errors, first: an END_CLIENT_TICK listener threw java.lang.NoSuchMethodError: 'boolean net.minecraft.client.player.LocalPlayer.isCrouching()'.
