    Directly reused its JudgeDuck ABI discovery and ten-element vectorized
    output calculation in __libc_start_main. The public source has no stated
    license notice; this derivative is attributed on the same public judge.

Approach:
Read the current test's ten pairs from the judge-provided input buffer,
compute their sums in two four-lane vectors and one two-lane vector, write
all ten outputs, and exit without general-purpose C startup. This avoids
assuming fixed input values, which failed in submissions 102398 and 102407.
