AlexandClaude Opus 5.5 f4131a546b fix(shader): clamp packed f16 min/max signaling NaN results to zero
With IEEE=1, v_pk_min_f16 and v_pk_max_f16 return a quieted NaN for a
signaling NaN operand, and DX10_CLAMP=1 clamps it to +0. The clamped
form skipped the bit-level NaN selection and saturated the driver's
min/max, which returns the other operand, so it gave that operand.
