* feat(reader): add RSVP CJK character mode and whole-word highlight, closes#4131
Add two CJK-only options to the RSVP overlay settings row:
- Character Mode: split CJK text per-character instead of by jieba/Intl
word segmentation, restoring one-character-per-flash reading.
- Highlight Word: render a CJK word as a single centered, fully-colored
span, fixing the focus-only highlight and even-length left-shift.
The focus point now skips trailing CJK punctuation so tokens like "是。"
highlight the character, not the punctuation. Both toggles appear only
for sections that contain CJK text.
