Keep settings-only workspace manifests scoped to the root package when checking dependency status, filtering projects, and completing --filter values.
These call sites previously passed an undefined package pattern to the projects reader, activating its recursive default even though config had already defined settings-only workspaces as root-only. Preserve the projects reader default for other callers and apply the root-only fallback only at the three manifest-aware boundaries.
