VO: Agrarian Reform

[1.2.0+build.2] - 2026-04-17

Fixed

• CRITICAL: Moved BlockColorsMixin to client-only mixin array — previously in shared array, causing ClassNotFoundException crash on dedicated servers.
• Trample Logic: Removed agrarianreform$forceTrample HEAD inject which bypassed vanilla's mob_griefing GameRule and entity size checks, incorrectly allowing small mobs to trample farmland.
• Trample Logic: Cleaned dead comment block inside agrarianreform$wrapTurnToDirt — WrapOperation is now the sole soft-step protection mechanism, correctly cooperating with vanilla's trample criteria.
• Thread Safety: ContinuumManager.UPDATE_QUEUE migrated from ArrayDeque (not thread-safe) to ConcurrentLinkedQueue.
• Cleanup: Removed unused AgrarianReformFabricClient.java stub (not referenced by fabric.mod.json).
• Cleanup: Removed unused CompoundTag and HolderLookup imports from ContinuumData.java.
