Complete ComfyUI Custom Node Development Documentation

I used Devin to help me complete this part, but I'm not sure if it's correct and need someone to review this PR.

Overview

This PR completes the comprehensive enhancement of ComfyUI custom node development documentation, including both Chinese and English versions, focusing on backend (Python) and frontend (JavaScript) documentation improvements.

Major Changes

Chinese Documentation Completion

  • Enhanced tips.mdx: Complete development lifecycle, debugging techniques, performance optimization, and best practices
  • Expanded datatypes.mdx: Detailed LATENT datatype explanation, channel counts for different SD models, complete additional parameters list
  • Fixed javascript_hooks.mdx: Added proper apiUpdateHandlers links and explanations
  • Completed server_overview.mdx: Added correct documentation links for dynamic INPUT_TYPES
  • Significantly expanded snippets.mdx: Model operations, conditioning processing, batch operations, device and memory management
  • Greatly enhanced javascript_examples.mdx: Custom widgets, node communication, advanced UI customization, workflow operations
  • Improved workflow_templates.mdx: Best practices, multilingual support, automated workflow generation

English Documentation Completion

  • Enhanced tips.mdx: Complete development lifecycle, debugging techniques, performance optimization, and best practices
  • Expanded snippets.mdx: Modern node implementations using ComfyNodeABC, advanced patterns, model operations, and batch processing
  • Significantly enhanced javascript_examples.mdx: Custom widgets (slider, file upload), server-client communication, advanced UI customization, workflow operations
  • Addressed all TODO comments: In datatypes.mdx, javascript_hooks.mdx, server_overview.mdx, and javascript_objects_and_hijacking.mdx
  • Added comprehensive localization.mdx: Complete internationalization guide with backend and frontend integration
  • Fixed remaining links: Updated all placeholder links and TODO comments with proper documentation references

New Features

  • Localization Support Documentation: Created complete localization.mdx documentation including backend and frontend internationalization implementation
  • Modern Node Patterns: Modern node implementation examples using ComfyNodeABC base class and type annotations
  • Advanced JavaScript Patterns: Custom widgets, real-time communication, batch operations and other advanced frontend features
  • Performance Optimization Guide: Memory management, device conversion, batch processing optimization and other best practices

Technical Improvements
