fix: restore CJK wide character support in ZerolagInput overlay (#30)

Browse Source

Add charCellWidth/stringCellWidth helpers for Unicode-aware width detection,
fix makeLine to use for...of iteration with visual column positioning, and
fix line splitting in _render to use visual column widths instead of string
length. CJK/fullwidth characters now correctly occupy 2 cell widths.
