Implements layout-independent bookmarks using character offsets within chapters instead of percentage-based positions. This allows bookmarks to restore to the exact position regardless of font size or orientation changes. Adds TOC navigation helpers, book progress calculation based on spine item sizes, and a NONE BidiBaseDir option for pre-reordered text. Legacy bookmarks without character offsets fall back to percentage-based positioning.
