v2.3.3 - Vehicle Anti-Cheat Whitelist Rework for 26.2

Fix

• Vehicle anti-cheat whitelist was silently not working on 26.2: the fix intercepted isVehicleMovingTooFast and checkVehicleMovement in ServerGamePacketListenerImpl, but those methods were removed in 26.2 — the moved too quickly vehicle check is now inlined inside handleMoveVehicle as if (movedSqr - velLenSqr > 100.0 && !isSingleplayerOwner()). The mixin targets no longer matched, so the whitelist never applied.
• Rewritten as a scoped @Redirect on the single isSingleplayerOwner() call site inside handleMoveVehicle: when the player's root vehicle is whitelisted it returns true, skipping the check for that vehicle. Other call sites of isSingleplayerOwner() (player movement checks, difficulty/gamemode permission checks) are untouched.
• Mixin defaultRequire restored to 1: the redirect target was verified against minecraft-server-patched-26.2.0.45-beta.jar, so a future mapping change will fail loudly at startup instead of silently disabling the fix.
