Add MiniMax M2.7 and M2.7-highspeed models to the STRIX_MODEL_MAP for
strix/ prefix shortcuts, auto-detect MINIMAX_API_KEY and set the MiniMax
API base URL (https://api.minimax.io/v1) when a MiniMax model is selected.
Includes provider documentation page, overview/README updates, 17 unit
tests and 3 integration tests covering model mapping, config resolution,
API key auto-detection, and end-to-end streaming completion.
- Change default model from gpt-5 to gpt-5.4 across docs, tests, and examples
- Remove Strix Router references from docs, quickstart, overview, and README
- Delete models.mdx (Strix Router page) and its nav entry
- Simplify install script to suggest openai/ prefix directly
- Keep strix/ model routing support intact in code
