Description

This PR adds Neurolink to the LLMs and ChatGPT section.

Neurolink is a Python-based production framework for building multi-agent LLM applications:

• 🐍 Pure Python implementation for seamless integration
• 🔄 Universal LLM provider support (OpenAI, Anthropic, Google, AWS Bedrock, Azure, and more)
• 🤖 Multi-agent orchestration with advanced coordination capabilities
• 🧠 Built-in RAG support for knowledge-augmented applications
• 🏭 Production-ready architecture with observability and monitoring
• 📦 Easy pip installation and minimal dependencies

Why this fits awesome-python:

• Python-first framework designed for the Python AI ecosystem
• Complements existing Python LLM tools like Haystack, LangChain, and LlamaIndex
• Focuses on production-ready, Pythonic APIs for building scalable AI applications

Positioning: Added after Haystack as a complementary multi-agent orchestration framework. Note: Entry may need repositioning based on current GitHub stars.

Thank you for maintaining this excellent Python library collection!
