[fix] Complete traditional to simplified Chinese character conversion (#5013)

* [fix] Complete traditional to simplified Chinese character conversion

Fixes issue where the automated translation system was incorrectly
mixing traditional Chinese characters into simplified Chinese (zh)
locale files after PR #4410 added zh-TW support.

Changes:
- Updated .i18nrc.cjs with explicit guidelines for AI model to
  distinguish between simplified and traditional Chinese
- Fixed 50+ traditional characters in zh locale files:
  - commands.json: 畫→画, 減→减, 筆→笔
  - main.json: 關→关, 刪→删, 複→复, 製→制, 輸→输, etc.
  - settings.json: 舊→旧, 標→标, 選→选, etc.

Completed the systematic conversion work started in PRs #5005 and #4865
without overwriting any human translator decisions.

Fixes #5010
