Run an end-to-end install+update regression test for Meta Skill Installer.

Goal: use a real ClawHub skill and verify install, review, and update flow.
Reference page: https://clawhub.ai/odrobnik/codexmonitor

Requirements:
1. Search ClawHub for CodexMonitor and select the matching skill slug.
2. Stage-install to a temporary directory and run security review:
   DATA_DIR="${SMC_DATA_DIR:-$HOME/.super-multica}"
   node "$DATA_DIR/skills/meta-skill-installer/scripts/review-skill-security.mjs" "<staged skill path>"
3. If riskLevel is safe, install to "$DATA_DIR/skills".
4. Verify "$DATA_DIR/skills/<slug>/SKILL.md" exists.
5. Run an update for the same slug in managed dir:
   clawhub update "<slug>" --workdir "$DATA_DIR" --dir skills --force
6. Run security review again on the final installed path.
7. Return: slug, initial riskLevel, update executed (yes/no), final path.
