feat: add ceil, cos, sin, sqrt, isNan native methods and division-by-zero tests

Browse Source 
Implement five new Num methods (ceil, cos, sin, sqrt, isNan) in wren_core.c and register them on the Num class. Add corresponding test files for ceil, floor, is_nan, and sqrt. Extend divide.wren with division-by-zero edge cases (inf, -inf, nan). Remove stale TODO comments from minus, multiply, and plus tests.
