feat: add Math library with abs, ceil, floor, trig, and xorshift RNG Implement a new optional Math module for the Wren standard library, gated behind the WREN_USE_LIB_MATH flag (default on). The module provides double-precision math functions (abs, ceil, floor, int, frac, sin, cos, tan, deg, rad) and a xorshift-based pseudo-random number generator with srand/rand methods. Includes comprehensive test files for each function and an all_tests runner. 2015-01-22 16:41:19 +01:00			`IO.print(Math.frac(8)) // expect: 0`

			`IO.print(Math.frac(-12.34)) // expect: -0.34`
