//! V3938 (1.20.6 + 99) — schematic-relevant subset of `V3938.java`.
//!
//! Adds walkers for the arrow entities (`minecraft:spectral_arrow`,
//! `minecraft:arrow`): `inBlockState` -> BLOCK_STATE, and the new `item` /
//! `weapon` single-itemstack fields -> ITEM_STACK.
//!
//! Nothing non-schematic is present in this version.
//!
//! VERSION = MCVersions.V1_20_6 (3839) + 99 = 3938.
