Trade Choice

Added

• Bundled vanilla 26.2 trade snapshot inside the JAR (assets/tradechoice/fallback/vanilla_trades_26.2.json) — covers all 13 villager professions across 5 levels + 3 wandering-trader profiles (68 trade sets) and the 40 enchantments in vanilla's tradeable enchantment tag, each annotated with max_level.
• New VanillaTradeSnapshot loader (lazy singleton, double-checked locking) for accessing the bundled snapshot data via the classpath resource.
• Three-tier fallback resolution in TradeWishlistScreen.buildEntries(): canonical TRADE_SET registry lookup → bundled vanilla snapshot → live MerchantMenu offers as last resort.

Fixed

• Multiplayer crash on dedicated servers that don't sync the TRADE_SET dynamic registry to clients (e.g., non-vanilla dedicated server). The Wanted trade panel previously threw IllegalStateException: Missing registry: ResourceKey[minecraft:root / minecraft:trade_set] on non-vanilla servers; it now degrades gracefully through the bundled snapshot.
• Tier-3 MerchantMenu fallback deduplication: multiple live offers of the same enchantment at different levels (e.g., Efficiency I / II / III) no longer render as duplicate wishlist rows — enchant levels collapse to 0 for WantedTrade equality, matching the canonical and snapshot paths.
• Tier-3 MerchantMenu fallback enchantment picker: entryMaxLevels now look up the enchantment's real maximum level from the bundled snapshot instead of being hardcoded to 1, so the level picker on enchantment rows renders the correct range.
