Under bash with set -euo pipefail, source <(cmd) process substitution doesn't reliably set variables in the caller's scope. The variables stay empty and -u (nounset) crashes the script. eval "$(cmd)" works correctly in both bash and zsh. Fixes: gstack-review-read, gstack-review-log, gstack-slug comment, gen-skill-docs.ts resolver functions, and regression tests.

# gstack-slug — output project slug and sanitized branch name

# Usage: eval "$(gstack-slug)" → sets SLUG and BRANCH variables
|

# Or: gstack-slug → prints SLUG=... and BRANCH=... lines

# Security: output is sanitized to [a-zA-Z0-9._-] only, preventing

# shell injection when consumed via source or eval.
