Add internationalization support for help view and implement help rendering logic

- Introduced `help-i18n.js` for managing translations in Chinese and English for the help view.
- Created `help.js` to render the help view, including command categories, workflow diagrams, and CodexLens quick-start.
- Implemented search functionality with debounce for command filtering.
- Added workflow diagram rendering with Cytoscape.js integration.
- Developed tests for write-file verification, ensuring proper handling of small and large JSON files.

 - Learn from existing implementations
 - Stop after 3 failed attempts and reassess
 - **Edit fallback**: When Edit tool fails 2+ times on same file, try Bash sed/awk first, then Write to recreate if still failing

+## Learning the Codebase
+
+- Find 3 similar features/components
+- Identify common patterns and conventions
+- Use same libraries/utilities when possible
+- Follow existing test patterns
+
+## Tooling
+
+- Use project's existing build system
+- Use project's test framework
+- Use project's formatter/linter settings
+- Don't introduce new tools without strong justification
+
+## Content Uniqueness Rules
+
+- **Each layer owns its abstraction level** - no content sharing between layers
+- **Reference, don't duplicate** - point to other layers, never copy content
+- **Maintain perspective** - each layer sees the system at its appropriate scale
+- **Avoid implementation creep** - higher layers stay architectural
