-/**
- * Footnote diagnostics for imported Markdown (issue #166).
- *
- * A PURE, fence-aware text scan (independent of the Markdown->ProseMirror
- * conversion path, so it reports the same problems for `create_page`,
- * `update_page` and `import_page_markdown`). It never changes the document — the
- * importer still creates the page; this only surfaces footnote problems to the
- * caller so an agent can fix its own markup instead of shipping broken footnotes.
- *
- * Detected problems:
- *  - danglingReferences: a `[^id]` reference with no `[^id]:` definition.
- *  - emptyDefinitions:   a `[^id]:` whose (kept) text is empty/whitespace.
- *  - duplicateDefinitions: an id defined by two or more `[^id]:` lines (only the
- *    first is kept on import — first-wins; see extractFootnotes).
- *  - referencesInTables: a `[^id]` marker found in a GFM table row (heuristic:
- *    the line, trimmed, starts with `|`) — footnotes in table cells often do not
- *    render as expected.
