It also adds rollback if a step fails partway through, which matters for anyone…

Over on last30days-skill, the hardening theme continues with two scanner-driven fixes: PR 941 upgrades a text-processing dependency to patch a high-severity denial-of-service vulnerability, and PR 944 tightens command handling in the run engine after semgrep flagged a dangerous exec pattern.
