QCB - Quick Channel Bar

[Improved]
Renamed from MtjChatBar to QCB (QuickChannelBar). Slash commands are now /qcb and /quickchannelbar. After installing, log in once with both add-ons enabled so settings migrate to QCB (chat copy / dice history are not migrated), then disable or delete the old MtjChatBar folder. Leaving both enabled shows two channel bars.
"Show player level" now appears as [70][Name] before the name; levels for players you've seen are remembered locally for a while.
Settings open in a standalone window via the minimap button or slash commands (no longer listed under ESC → Options → AddOns).
[Fixed]
Fixed an occasional error when searching in the system Options UI.


【优化】
插件由 MtjChatBar 更名为 QCB（QuickChannelBar / 快速频道条）；斜杠改为 /qcb、/quickchannelbar。装上新版后请先与旧包一起进游戏一次，旧设置会自动迁到 QCB（不含聊天复制 / 掷骰历史），再禁用或删除旧文件夹 MtjChatBar；两包一直同开会出现两条频道条。
「显示玩家等级」改为名字前显示如 [70][名字]；见过的玩家等级会本地记住一段时间。
设置改为小地图按钮或斜杠打开自建窗口（不再出现在 ESC → 选项的插件列表）。
