Arnaud Gourlay d4e0f354da Single inverse rotation in TurboQuant symmetric L1 scoring (#9835)
The inverse Hadamard rotation is linear, so it distributes over
subtraction: |R'd1 - R'd2| = |R'(d1 - d2)|. Subtract the dequantized
vectors in rotated space and inverse-rotate the difference once,
instead of inverse-rotating both vectors per score call.
