fix(r-arm): keep here optional, not an import [skip auto-tag]

The previous commit put here in Imports to mirror rmorie, which makes it a hard dependency. It is only ever reached inside tryCatch(here::here(), error = function(e) NULL), so it is optional by construction and belongs in Suggests, where it still satisfies the undeclared-import check. The vendored arm gains no hard dependency from any of this work: the other seven entries are Suggests, which are never installed or loaded with the package. tools:::.check_packages_used remains clean.
