Gemini 3 Pro

Migrate the pinned Gemini 3 Pro example to Gemini 3.1 Pro Preview before using web search and SQLite chat history.

Google shut down Gemini 3 Pro Preview on March 9, 2026. The pinned gemini-3-pro-preview ID currently aliases to gemini-3.1-pro-preview; replace it explicitly before running.
