On Windows on ARM64, x64-emulated Git Bash intermittently deadlocks in MSYS2's fork() emulation, and ./setup hung in the loops that read every SKILL.md name through grep | sed | tr plus a basename (about four process starts per skill). A sourced helper, bin/gstack-skill-name.sh, reads the name with a bash read loop and no subshell; gstack-patch-names, setup's link and cleanup loops and gstack-uninstall's inventory use it and parameter expansion instead of basename. Codex links keep their directory names. Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>
