feat: replace Wren Range class with native C object for performance

Browse Source 
Remove the Range class definition from corelib.wren and implement it as a native C type with ObjRange struct, adding native methods for from, to, min, max, iterate, and iteratorValue. Move range operator handling from Num class to native num_dotDot and num_dotDotDot functions. Update VM to support OBJ_RANGE type in marking, printing, and type checking. Add comprehensive test suite for range operations including ordered, backwards, and exclusive ranges.
