Adds Doxygen Doc Generator AI agent

[viborc]

This commit adds a comprehensive prompt for generating Doxygen-style documentation for Python code. Doxygen is a documentation generator that extracts structured comments from code to create reference documentation.

The AI Agent with this prompt does the following:

• Implements the ## comment style specifically for Python
• Defines documentation structures for functions, classes, and modules
• Provides templates for @brief summaries, parameter descriptions, return values, and exceptions
• Includes guidelines for documenting class variables and instance variables
• Outlines a 4-step documentation process: code analysis, critical elements, quality writing, and consistency
• Emphasizes explaining the "why" behind code, not just functionality
• Includes examples of proper @code usage for demonstrating implementation

On line 6, there's a missing closing quotation mark in the "File Search" tool entry:

"File Search,

Also make the file ".json"
