1.5.2 — no more empty batches

Fixed

• Mobs whose loot rolls "0 or 1" (phantom, and any table that only drops when a player lands the kill) could still produce an empty batch. The expected-value fallback now rolls with the killer in the loot context, and if every roll still comes up zero it produces one item from the table instead of nothing.
• Both 1.21.1 and 26.1.2 builds are included.
