Elementwise tolerance check: $|a - b| \le \mathrm{atol} + \mathrm{rtol} \cdot |b|$.

Composite over sub_op + abs_op + mul_op + add_op + less_equal_op — no dedicated kernel required. rtol and atol are materialised as same-shape constant tensors so the multiply does not depend on any scalar-broadcast support in the binary ops. Returns a bool tensor; not differentiable.
