### main branch

- Expanded `ANTHROPIC_MODELS` list with Claude Opus 4.1/4.5/4.6/4.7 dated variants and Claude Sonnet 3.7 so the Anthropic API key auto-detection (`models.sanity_check_models`) recognises them.
- Added `gemini-3.1-pro-preview` and `flash-lite-3.1` model aliases pointing at `gemini/gemini-3.1-pro-preview` and `gemini/gemini-3.1-flash-lite` respectively.
- Added `gemini-3.1-pro-preview` and `flash-lite-3.1` model aliases pointing at `gemini/gemini-3.1-pro-preview` and `gemini/gemini-3.1-flash-lite` respectively.
- Added support for Claude 4.5/4.6 models and updated model aliases (sonnet/haiku/opus).
- Expanded Gemini model support with 2.5 Flash and Flash‑Lite, added Gemini 3 preview models, and updated the flash alias to gemini/gemini-flash-latest.
- Added DeepSeek Reasoner model and updated DeepSeek model metadata with costs and prompt caching.
