Please add DeepSeek R1 model

As I’ve suggested here, I know it is be impossible to make all models be accessible in composer mode: But sometimes we do need to integrate diff features from various models—

For example, the current Claude sonnet 3.5 is good for quick responses but would run into a dead cycle when facing a complex issue. o1 and deepSeekR1 are good for complex issues, though, but respond slowly. So, if both chat and composer mode context could be shared, then they can interact to gain the best result.
