Switch KOReader sync progress mapping from chapter matching to XPath-based mapping. - resolves KOReader positions using real XHTML ancestry paths - supports paragraph-based upload mapping with text offsets where needed - passes the current paragraph index into sync so uploads map back to KOReader more accurately No HTTP client changes are included. No reader-state or resume-flow changes are included. --------- Co-authored-by: jpirnay <jens@pirnay.com>
