Upgrade harness-kit in user's project to version bundled in the installed plugin.
Plugin cache has no git remote, so newest source comes from the plugin itself. Order:
/plugin update harness-kit first (fetches newer plugin from marketplace).bash "${CLAUDE_PLUGIN_ROOT}/setup/update.sh" "${CLAUDE_PROJECT_DIR}"
update.sh in plugin cache (no .git) falls through to reinstall of the bundled version, expected. It backs up existing .claude/settings.json and reports version delta via .claude/.hk-version.
Relay output verbatim. Tell user to restart Claude Code after.
If user wants a newer harness and plugin already current, point them at /plugin update harness-kit then rerun this.
