Add Config to Disable Model Mapping (#41)
Introduce a new environment variable, DISABLE_MODEL_MAPPING, when enabled removes the OpenAI -> Gemini Model mapping and provides access to the named gemini models directly. Moved model mapping logic to its own `models.go` file inside the adapter package. Additionally, fixed a bug where responses would return the gemini model name even though model mapping was enabled.
