Extend zh-tw vocab guard with 24 more S-Chinese loan-word patterns

Each pattern uses Traditional characters but is Simplified-Chinese
vocabulary — a plain T-vs-S character pass cannot catch them.

Hardware:
  硬件 → 硬體   主板 → 主機板   顯卡 → 顯示卡
  硬盤 → 硬碟   軟盤 → 軟碟    光盤 → 光碟

Printing / I/O:
  打印 / 打印機 → 列印 / 印表機
  串口 → 序列埠

Crypto / data:
  密鑰 → 金鑰
  數組 → 陣列
  變量 → 變數 (excludes `不變量` = invariant via negative-lookbehind;
              `不變量` is the math / formal-verification term and is
              accepted in TW)
  字節 → 位元組
  比特 → 位元 (excludes `比特幣` = bitcoin via negative-lookahead;
              the bitcoin loan word is accepted in TW)

Code / async:
  注釋 → 註解 / 註釋     模板 → 範本
  跟蹤 → 追蹤           異步 → 非同步

UI / display / media:
  圖標 → 圖示
  高清 → 高畫質
  寬屏 → 寬螢幕
  信道 → 通道 / 頻道
  鏡像文件 → 映像檔
  文件夾 → 資料夾
  短信 → 簡訊

Caught one real offender in scripts/regen_llm_security_batch_zh_tw.py:
  "讓 origin-entity 不變量明確化…" was OK (math invariant); a separate
  `…的變量資訊化…` line WAS S-Chinese drift and is fixed to `變數`.

.claude/agents/language-vocabulary-check.md table now mirrors the
24 additions so future LLM sessions get the same lexicon when they
read the agent doc instead of the regex set.

510/510 tests pass.
