fix(frontend): improve chat math rendering (#3557)
* fix(frontend): improve chat math rendering

* fix(frontend): refine math rendering stability

* fix(frontend): address review feedback on math preprocessing

- Fix escaped-backslash blind spot: consume \\\\ as a unit so \\( and
  \\[ are not mis-interpreted as math delimiters when the backslash
  itself is escaped.
- Thread inInlineCode state across lines so multi-line backtick code
  spans are protected from delimiter conversion.
- Remove double math normalization: preprocessStreamdownMarkdown now
  only handles Mermaid; math normalization lives solely in
  ClipboardSafeStreamdown, preventing non-idempotent double passes.
- Wire parseIncompleteMarkdown to isLoading in MarkdownContent so
  Streamdown's streaming-incomplete-math handling is actually active
  during streaming.

* fix(frontend): address streamdown math review issues

* refactor(frontend): move streamdown preprocessing out of ai elements
