Add two debug/profiling tools to 05-custom.sh: - gops: live process diagnostics (list Go processes, dump stacks, force GC) - benchstat: statistically sound benchmark comparison via pprof Both tools baked into /usr/local/bin at build time. Build verified: go1.26.3, all 19 tools confirmed on PATH. - rootfs/root/docker/setup/05-custom.sh: add gops and benchstat installs rootfs/root/docker/setup/05-custom.sh
