Detailed Description

Forward-propagates floating-point constant scalars into their uses.

A scalar container that is defined by a single constant assignment (ConstantNode -> assign -> scalar) is treated as holding that constant. Every downstream computational read of the scalar is rewritten to read the constant directly, which in turn enables library-node simplifications (e.g. GEMM alpha == 1 / beta == 0) and later folding.
