Round 7: 21 more patterns — 復/複 confusion, number bases, syscalls, UI

The most impactful catch this round: S-Chinese conflates 復 (= "again")
and 複 (= "duplicate"). The compound 復制 (S) is widespread but should
be 複製 in T-Chinese — 復 is the wrong radical for "duplicate". Same
applies to 復用 vs 重用. These two were in the agent doc table but
never made it into the test regex set; that gap closes here.

Patterns added:

`復` / `複` distinction:
  復制 → 複製   (very common — S `復` ≠ T `複`)
  復用 → 重用
  編寫 → 撰寫

Number bases:
  二進制 → 二進位
  八進制 → 八進位
  十進制 → 十進位
  十六進制 → 十六進位
  進制 → 進位  (general; excludes the 4 specific compounds above
                via negative-lookbehind)

Serial / parallel / stack / files:
  串行 → 串列          堆棧 → 堆疊
  二叉堆 → 二元堆積     壓縮文件 → 壓縮檔

Kernel / syscalls / messaging:
  用戶態 → 使用者模式
  系統調用 → 系統呼叫
  調用 → 呼叫  (excludes 失調用 / 強調用 via negative-lookbehind)
  反向工程 → 逆向工程
  私聊 → 私訊

UI controls / parts / identifiers:
  控件 → 控制項
  部件 → 元件
  標識 → 標示  (excludes 標識符 already covered)
  圖元 → 像素

Tried and reverted:
  跨度 → 跨距 / 範圍 — turned out to false-positive on TW-acceptable
  「時間跨度」 in regen_llm_security_batch_zh_tw.py. 跨度 is standard
  TW vocabulary too; removed from the pattern set.

s_only_patterns now holds 233 regex entries across 26 sub-sections in
the agent doc table. No new offenders in zh-tw content.

510/510 pytest pass.
