When the player's hand is empty, add now automatically creates a Paper item named "描述便签" (Description Note) as a blank canvas, instead of displaying an error.

Implemented translateAmpersandCodes utility to convert & format codes (e.g. &c, &l) to Minecraft § codes, supporting all 16 colors (0–9, a–f), 5 styles (k–o), and reset (r), with && escaping to a literal & character.

实现 translateAmpersandCodes 工具方法，将 & 格式化码（如 &c、&l）转换为 Minecraft § 码，支持全部 16 种颜色（0–9、a–f）、5 种样式（k–o）和重置（r），&& 转义为字面 & 字符。

Fixed a bug in translateAmpersandCodes where a missing continue statement after format-code replacement caused &c to be incorrectly translated to §&c instead of §c.

修复 translateAmpersandCodes 中因格式化码替换后缺少 continue 语句，导致 &c 被错误翻译为 §&c 而非 §c 的问题。
