giles 80c21cbabb js-on-sx: String fixes — fromCodePoint, multi-arg indexOf/split/lastIndexOf, matchAll, constructor, js-to-string dict ...

- String.fromCodePoint added (BMP + surrogate pairs)
- indexOf/lastIndexOf/split now accept optional second argument (fromIndex / limit)
- matchAll stub added to js-string-method and String.prototype
- String property else-branch now falls back to String.prototype (fixes 'a'.constructor === String)
- js-to-string for dict returns [object Object] instead of recursing into circular String.prototype.constructor structure
- js-list-take helper added for split limit

Scoreboard: String 42→43, timeouts 32→13, total 162→202/300 (54%→67.3%). 529/530 unit, 148/148 slice.
