* fix(frontend): render user messages as plain text and cap blockquote nesting
User messages are typed or pasted plain text, not authored Markdown, but
they were rendered through the full Streamdown pipeline. Pasted source
files got fragmented (indented chunks become code blocks, paragraphs
collapse and lose indentation), "$...$" spans were KaTeX-ified, and a
message with thousands of nested ">" markers overflowed the call stack
in marked's recursive blockquote lexer, permanently crashing the thread
on every load.
Render human message content verbatim with pre-wrap instead, and cap
blockquote nesting at 100 levels at the Streamdown chokepoint so model
output cannot trigger the same recursion either.
Closes#3500
* fix(frontend): absorb marked lexer crashes with a render fallback boundary
Review found two gaps in the nesting cap: marked's list and blockquote
tokenizers are mutually recursive, so a list marker in front of the
quote chain ("- > > > ...") bypassed the blockquote-only regex and
still overflowed the stack; and the line-based rewrite was fence-blind,
silently truncating literal ">" runs inside code blocks.
Add an error boundary around Streamdown that renders the raw content as
plain pre-wrap text when rendering throws (retrying on the next content
change), keep the cap as a fast path for the dominant pure-">" case,
and make it skip fenced and indented code lines.

For human messages, disable remark-gfm autolink feature to prevent
URLs from incorrectly including adjacent text (especially Chinese
characters) as part of the link. This ensures that when users input
"https://example.com 帮我分析", only the URL becomes a link.
