Meta Vens	c65725da8f	CultMath Cycles: arcsine, arccosine and arctan2 with Cycles' guards; per-function oracle seeds; the ruled unfused reference, empty Tolerances and the class table ... Fixtures and the regenerated GLSL follow in the next commit, so the tests that read the new rows (InverseTrigonometry..., OperandStreams...) are red at this commit.

Meta Vens	51c5da11c4	CultMath: cycles_modulo is exact (power-of-two subtraction, no quotient form); RGB to BW coefficients are Blender's; oracle.py pins the SSE4.2 CPU kernel ... The oracle's first fixtures showed Cycles' AVX2 kernel fuses multiply-adds and its film zeroes non-finite results; the tool now exits 4 off the SSE4.2 kernel (CYCLES_CPU_NO_AVX2=1) and the test skips cases Cycles cannot report. The Unity copy of CultMath.hlsl carries the new include. Builds. Fixtures and CultMath.Cycles.glsl are still to come.
