ui.search only matches the document body: text in headers, footers and footnotes is never found #4121

What happened?

superdoc.ui.search.find() (the find/replace surface) returns matches from the body story only. Text that is painted on the page in a header, footer or footnote is never matched, so the find bar reports 0 results for words the reader can see.

Expected: matches in every visible story, as the reader sees them on the page, or at least an option to include headers, footers and notes.

Actual: only body matches are counted and navigated. SearchQueryOptions has caseSensitive, includeTrackedDeletions and regex, and no option for story scope.

Steps to reproduce

1. Open the attached search-stories-repro.docx. It is one page of synthetic text. Each story holds a marker word that appears nowhere else:
   • body: alphabody
   • header: bravoheader
   • footer: charliefooter
   • footnote: deltafootnote
   • sharedmarker appears once in the body and once in the header
2. Run superdoc.ui.search.find(word) for each word and read getSnapshot().total once it settles.

All four marker words are present in the painted page's DOM.
