refactor: merge zh/en data into single multi-lang structure

- Restructure cases.json with multi-lang fields: name, description, summary
  - Each field now supports { "zh": "...", "en": "..." } format
- Update build.py to output single data.js with multi-lang data
- Update index.html with client-side language switching
  - Single page supports both languages via localStorage
  - getText() helper extracts text based on current language
- Remove separate data_en.js and index_zh.html (no longer needed)
- Simplify edit_tool server.py for single data.json
