/**
* Maps a bundle URL onto the staged namespace layout. Bundle URLs carry their
* namespace in the path (`…/bundles/<account>/<gateway>/<workspace>/…`); the
* staged layout mirrors it under `<bundleDir>/<account>/<gateway>/…`. The
* namespace is taken from the URL itself — unlike the runtime-identity
* resolution, this answers "which staged directory do these bytes live in?"
* rather than "is this my namespace?" — and the result is contained within
* the account/gateway directory. Returns null for foreign shapes.
