Skill blocks source bin/gstack-codex-probe and bin/gstack-egress-lib.sh into
the host's shell. Under zsh (macOS default) BASH_SOURCE is empty, so Codex
model selection resolved /../scripts/... and every outside pass reported
CODEX_MODEL: invalid; the egress lib resolved to the caller's cwd. Resolve
the file once at source time (BASH_SOURCE under bash, %x under zsh), and
replace the bash-only ${!name} indirection in the auth probe. A free test
derives every sourced helper from the generated skills and sources each
under bash and zsh.
