Added Chinese (zh-cn)Language Support

[YASHRDX0001]

This PR adds full Chinese Simplified (zh-CN) language support to DrawDB, providing a complete and accurate translation for users across China and other Chinese-speaking regions.

All strings have been translated following DrawDB’s established i18n structure and match the completeness and consistency of other supported languages.

What's Included

1. New Language Support

• Added zh-cn.js locale file
• Added language entry to i18n.js
• Registered in both the languages array and the resources object

2. Translation Quality & Structure

• All interpolation placeholders preserved

  • e.g., {{tableName}}, {{fieldName}}, {{typeName}}, {{refName}}, etc.

• Structure exactly mirrors the English source file

• Terminology kept consistent across:

  • Core menus & actions (file, edit, view, help)
  • Tables, relationships, enums, notes, subject areas
  • Validation messages, dialogs, and warnings
  • DBML view, multiselect, and bulk operations
  • Sharing, export, import, timeline, tasks, and version history

• Ensures the language appears in the UI and loads correctly

3. Language Details

• Name: Chinese (Simplified)
• Native Name: 简体中文
• Code: zh-CN
• Speakers: ~1 billion (China, Singapore, Malaysia, and Chinese-speaking communities worldwide)

Testing

• Verified all keys and placeholders are correctly translated
• Confirmed structure matches other locale files
• No syntax errors in JavaScript files
• Build runs without issues

Why Chinese?

Chinese (Simplified) is one of the most widely spoken languages in the world, with over a billion native speakers and a rapidly growing developer community. Adding Chinese language support makes DrawDB more accessible to engineers, students, and database designers across China and other Chinese-speaking regions, expanding its usability in one of the largest and most influential tech ecosystems globally.
