/**
 * Fold a variadic application of a 2-argument shader builtin (`min`/`max`)
 * into a left-nested tree of 2-argument calls: `max(max(a, b), c)`. GLSL and
 * WGSL do not accept a 3+-argument `min`/`max`, so emitting `max(a, b, c)`
 * would be invalid shader source.
 *
 * Each GENERATED call is validated as it is produced, against the ORIGINAL
 * operand shapes (`gpuOperandShape`) rather than against the emitted source:
 * once the fold has nested the calls, the CE operand positions no longer line
 * up with the emitted argument positions, and the generic gate's source-level
 * reconstruction (`gpuSourceIsVector`) cannot see a vector in a BARE
