Gemini Interactions - Deep Research multi-turn

"""
Gemini Interactions - Deep Research multi-turn
===============================================

Continue a Deep Research interaction across turns. Each response carries an
interaction_id; the next turn references it via `previous_interaction_id`
so the API only receives the new user message (the server already has the
prior research and its citations).

Persisting the interaction_id requires a db (e.g. SqliteDb): the assistant
message stores it under provider_data, and the next turn reads it back.

A common Deep Research multi-turn flow:
  1. Turn 1: ask for a plan (collaborative_planning=True returns just the plan)
  2. Turn 2: approve or refine the plan
  3. Turn 3+: drill into specific sections of the report

For the dedicated plan/approve flow see deep_research_collaborative_planning.py.
