[Feature Request] firestore agent memory

[jeffbryner]

Problem Description

I'd like to use serverless databases for agent memory. Being in a google environment, firestore is ideal.

Proposed Solution

Provide a firestore provider (agno/db/memory/firestore)

Alternatives Considered

Using other providers requires a server or a file store (sqlite)

Would you like to work on this?

I'll fork and provide a pull request.
