Implementation of VectorDB within codegate code

[lukehinds]

Now that the VectorDB is packaged in #62 , code is developed to perform a similarity search for package name, and if present create an augmented quote + RAGQuote which is then sent to the LLM.

Data will consist of: Package Name, Ecosystem and Description.

This work requires #47 to be able to filter and parse library / module names form the code snippets.
