[ZhaoHeh]

Summary

This PR introduces significant enhancements to the GUI Agent SDK, focusing on

• action parsing capabilities;
• coordinate normalization;
• comprehensive utility functions
  The changes improve the robustness, flexibility, and maintainability of the GUI agent system.

✨ Key Features

1. JSON Function Call Parser Support

• Added JSON function call parsing capabilities in ActionParserHelper.ts
• Introduced parseFunctionCallString() and parseRoughFromFunctionCall() methods
• Enhanced action parsing with better error handling and validation
• Improved compatibility with different action input formats

2. Coordinate Normalization System

• New utility: coordinateNormalizer.ts with defaultNormalizeCoords() function
• Core function: normalizeActionCoords() for processing BaseAction coordinates
• Supports normalization of point, start, and end coordinate fields

3. Action Standardization Framework

• New utility: standardizeNames.ts with comprehensive action type mapping
• Standardizes 50+ action type variations (click, double_click, scroll, etc.)
• Normalizes action input parameter names across different formats
• Action-specific input mappings for better consistency

4. Enhanced Utility Functions

• serializeActions.ts: Action serialization utilities
• systemPromptProcessor.ts: System prompt processing capabilities
• sleep.ts: Async sleep utility for timing operations
• Improved base agent and operator classes with better initialization
