fix(export): robustly export reasoning and handle errors (#9221)

* fix(export): robustly export reasoning and handle errors

* fix(export): normalize <br> to newline before notion parsing

* feat(i18n): add notion truncation and unify export warn keys

* refactor(export): add typing, state guards, and error logging

* fix(export): preserve existing <br> in reasoning when convert to html

* feat(export): add DOMPurify sanitization for reasoning content

* chore(deps): remove unused @types/dompurify dev dep

* chore(deps): remove dompurify dependency

Remove dompurify from package.json and yarn. The changes
delete dompurify entries and simplify the lockfile resolution so the
project no longer declares dompurify as a direct dependency.

This cleans up unused dependency declarations and prevents installing
dompurify when it is not required.
