bench_simd.py re-invokes `maturin develop` at runtime to compare portable vs SIMD builds, which requires an active virtualenv. CI installs into system Python so maturin develop fails with "Couldn't find a virtualenv". --skip-simd avoids this; the SIMD comparison is optional profiling, not a correctness gate.
