    /// - When `--load-ny-plugins` or `NYASH_LOAD_NY_PLUGINS=1` is set, best‑effort
    ///   loads Nyash scripts listed under `nyash.toml`'s `ny_plugins`.
    ///
    /// Side effects:
    /// - Sets `NYASH_USE_PLUGIN_BUILTINS=1` if unset, to allow interpreter side creation.
    /// - Updates `NYASH_PLUGIN_OVERRIDE_TYPES` env var (merged values).
