Greptile Summary

This PR localizes recently added English interface strings into Simplified and Traditional Chinese.

• Translates process-monitoring labels and elapsed-time messages.
• Translates terminal scrollbar, copy-exclusion, and horizontal-scroll-margin settings.
• Preserves all interpolation placeholders and localization keys.

Confidence Score: 4/5

The PR appears safe to merge, though the Traditional Chinese strings should be revised for locale-appropriate terminology and orthography.

Runtime behavior, localization keys, and placeholders remain intact; the only accepted concern is non-blocking translation quality in src/lang/zh-hant.json.

Files Needing Attention: src/lang/zh-hant.json

Important Files Changed

Filename	Overview
src/lang/zh-cn.json	Replaces English fallback values with coherent Simplified Chinese translations while preserving keys and placeholders.
src/lang/zh-hant.json	Adds Traditional Chinese values, but several are mechanically converted Mainland Chinese terms rather than idiomatic Traditional Chinese localization.
