An env credential's Identity (".env / API_TOKEN") produced StorePath
imported/env/.env/api_token; gopass hides dot-prefixed segments from
`ls --flat`, so those entries were invisible to bundle.ListPaths and the
mandatory backup gate silently under-covered them (Hard Rule #1 violation).
slug() now strips leading dots per /-separated segment so incredigo can no
longer write a path that `ls --flat` hides. Locked in by
TestStorePathNoDotSegment.
