Subject: [PATCH 1/2] feat: add support for Gemini 3 models - Add
 gemini-3.1-pro-preview, gemini-3.1-flash-lite-preview, and
 gemini-3-flash-preview to supported models in config.ts - Update gemini.ts to
 use thinkingLevel: 'minimal' for Gemini 3 models for fast commit message
 generation - Update README.md to include new Gemini 3 models and descriptions

Subject: [PATCH 2/2] feat: add Gemini 3 support and sunset Gemini 1.5 models -
 Added support for Gemini 3.1 Pro Preview, 3.1 Flash Lite Preview, and 3 Flash
 Preview - Removed support for Gemini 1.5 Flash and 1.5 Pro models -
 Implemented thinkingLevel: 'low' for Pro models and 'minimal' for Flash
 models to ensure optimal performance and cost-efficiency - Updated README.md
 and config validation to reflect these changes
