feat(epub): Improve nov reader typography and layout
- Reduce variable-pitch font from 1.8x to 1.0x for normal reading size
- Add configurable margin percentage (cj/nov-margin-percent, default 25%)
- Calculate text width dynamically based on window size and margins
- Text now uses 50% of window width with 25% margins on each side
