trading-system

New

• /tradesearch — find offers three ways: "What can I get?", "What do they want?", or "Exact trade" with amounts on both sides. Results open in the normal board, so you still trade the usual way.
• Sort button on the board: newest first, largest amount, or best price per item.
• Search and clear-filter buttons on the board itself.
• Info page now shows how many offers match the filter and how many of your 4 slots are used.

Changed

• An active filter survives paging and backing out of an offer.
• Author credited in /version TradeBoard, the jar manifest and the startup log.

Fixed

• Duplicate /tradeboard:* commands no longer show up in tab completion or /help.
