fix: make aube installation non-fatal in setup.sh

aube@1.13.0 (published 2026-05-13) has a broken arm64 binary — the
@endevco/aube-linux-arm64 platform package declares bin/aubr but the
file doesn't exist in the tarball, causing npm install to fail with
ENOENT during preinstall.

Rather than pinning to a specific version, make the aube install
non-fatal so a broken aube release doesn't block the entire benchmark
suite (all 41+ jobs). If aube fails to install, a warning is logged
and the suite continues benchmarking all other package managers.
