Currently these commands silently fall back to the active node version when neither a version argument nor an `.nvmrc` resolves, making them invisibly dependent on shell state and impossible to script predictably (see #3755). Print a stderr deprecation warning in this case (suppressed by `--silent`) and continue with the active node version, so existing callers keep working. The follow-up change will turn this into a hard error; pass `current` explicitly (e.g. `nvm exec current node ...`) to silence the warning and lock in the new behavior now. Refs #3755
