Code Review

This pull request fixes an incomplete sentence in the DeepSeek v3.2 documentation, clarifying that DP attention is enabled by default for this model. The change is accurate and helpful. I've provided one suggestion to slightly rephrase the sentence for improved clarity and style. Additionally, while outside the scope of this PR's changes, you might consider removing the redundant --enable-dp-attention flag from the example launch commands in this file to align with the fact that it's enabled by default.

While the sentence is now complete and correct, it could be slightly rephrased for better readability and a more formal tone. Splitting the long sentence and replacing "so" with "Therefore" would improve clarity.

Suggested change

	- **DP Attention**: For DeepSeek V3.2 model, the kernels are customized for the use case of `dp_size=8`, so DP attention is enabled by default for better stability and performance. The feature of launching with pure TP is still under development.
