Add remark-breaks so Streamdown matches documented line breaks

[xhuajin]

Description

Add remark-breaks to the default remark plugin set so single line breaks render as <br> per the docs.

The documentation mentions that GFM preserves line breaks, but my tests show GFM does not retain line breaks. Line breaks in Streamdown are also merged into a single line. I added remark-breaks to preserve line breaks.
