fix(argo): wrap TEST_BIN pipeline in subshell + || true to suppress SIGPIPE

Browse Source 
`set -o pipefail` + `head -1` closing stdin produces SIGPIPE (exit 141)
from upstream `ls`/`grep`. The subshell + || true contains the failure
to the inner pipeline so the script's pipefail doesn't propagate it.

Sanitizer fired exit 141 immediately after the cargo build; nsys
reproduced the same exit on its parallel run, confirming the diagnosis.
