Epub tts fix (#103)

Browse source 
* build: bump version to 1.0.38 and improve CFI page lookup logic

* fix: resolve duplicate TTS audio and broken highlights in Vertical Mode

Updated the text extraction logic in epub_reader.js to pick only the most granular matching elements, preventing duplication when elements like <p> are nested inside <li>.
