 * Pin/unpin sub-commands as standalone skill shortcuts.
 *
 * Usage:
 *   node <scripts_path>/pin.mjs pin <command>
 *   node <scripts_path>/pin.mjs unpin <command>
 *
 * `pin audit` creates a lightweight /audit skill that redirects to /impeccable audit.
 * `unpin audit` removes that shortcut.
 *
 * The script discovers harness directories (.claude/skills, .cursor/skills, etc.)
 * in the project root and creates/removes the pin in all of them.
