Gemini Interactions - Multi-turn Conversation

"""
Gemini Interactions - Multi-turn Conversation
==============================================

Demonstrates server-side conversation history with the Interactions API.
After the first response, subsequent turns only send the new message
and reference the previous interaction via `previous_interaction_id`.
This enables implicit caching and reduces token costs.

Multi-turn requires a db (e.g. SqliteDb) so the interaction_id from each
turn's response is persisted on the assistant message and read back on
the next turn.
