Add new unit: AI Memory MCP servers

[Vasilije1990]

Hello,

I am a founder of cognee, an AI memory tool with an active MCP server implementation that allows any tool, coding assistant and more to create a memory layer on top of vector and graph stores.

I'd like to propose a section in the course that would teach the students the following:

1. How to set up portable MCP AI memory server they can re-use and enrich between flows, copilots, agents
2. How to load custom rules and instructions to the server
3. How to search their data and visualize it, and provide Human in the loop type feedback
