Email Auto-Responder with IMAP and Google Drive

# STEP 3 - MAIN FLOW

- Transform the email into Markdown format for optimal reading by the LLM model
- Email Summarization through DeepSeek R1 (any model can be used)
- I classify the email in such a way as to continue only with emails regarding general information about the company. In this way I can respond independently through the information obtained from the vector database
- I create a chain where I entrust the review of the email to a high-performance model designed for this purpose
- I send the response email
