Villager Trade Cycler

[1.0.3_hotfix] - 2026-04-21

Fixed

• Fixed server disconnects caused by custom payload size mismatch during trade rerolls.
• Restored packet compatibility by sending an empty reroll payload from the client.
• Added tolerant payload decoding on the server to handle both old and new payload shapes.
• Added safer server-side reroll error handling to prevent hard disconnects on unexpected exceptions.
