Every distinct sigdb bundle discoverable in the search dirs (see defaultSigDbPath) -- not just the
richest scope. So dropping an extra bundle next to the shipped default (a downloaded full-history
full.manifest.json.br, a custom *.manifest.json, or a standalone *.sigs.ndjson) makes flowR mount it
automatically. Manifests come first (scope-named leading, richest scope first), then standalone bundles; the
shard and dictionary files a manifest already owns are skipped. Deduped by filename, first search location wins.
