User pointed out their Google AI Studio dropdown shows gemini-3-pro, gemini-3.1-pro, gemini-3-flash and gemini-2.5-flash — not the longer preview names I shipped in v1.1.0:4. The menu was missing all the Flash variants entirely. Fix: - Add gemini-3.1-pro (short form, what AI Studio shows) - Add gemini-3.1-flash + gemini-3.1-flash-lite (the cheapest 3.x) - Add gemini-3-pro + gemini-3-flash (older tier, still available) - Pricing entries for all of the above (~$0.50/$3 per M for Flash) Pure data fix; no schema or behavior changes.
