New features: added generated footnote backlinks for default mode in EPUB, KFX/AZW8, PDF, and Markdown where supported.
- EPUB default footnotes now include backlink paragraphs at the end of each footnote section, using existing link-backlink styling.
- EPUB2/KEPUB floating footnote backlinks now render at footnote end instead of the beginning, preserving single-paragraph popup-compatible markup.
- EPUB3 default backlinks now use epub:type="backlink" and role="doc-backlink" while keeping footnote references as ordinary links, not popup noteref links.
- KFX/AZW8 default footnotes now generate backlink paragraphs but no longer emit Kindle popup markers, so default-mode footnote links navigate normally.
- KFX/AZW8 backlink templates now resolve .LocationNumber for backward footnote references by refreshing backlink text after footnote locations are known.
- Markdown default footnotes now emit reference anchors and backlink links; TXT remains unchanged.
- Fixed backlink ordering so later footnotes can link back to earlier footnotes without missing generated backlinks.
