hiclaw-test

This module is not overtly malicious, but it is structurally high-risk for supply-chain contexts: it executes arbitrary shell code by `source`-ing a user/environment-specified env file, and it then executes repository-controlled scripts after cloning/updating an unpinned upstream branch or selecting a potentially attacker-influenced local directory. If attacker control over ENV_FILE contents, REPO_DIR location, or upstream repository integrity exists, arbitrary code execution is feasible. If inputs and environment are fully trusted (e.g., locked-down CI), the practical risk is reduced.
