base_nesting

Bases may nest: any subdirectory that owns its own `.reqlan` is a child base.
Parent-base indexing includes only `.rq` files under the parent root that are * * not * * under
any child base root ( base-discovery.ts ownership exclusion ).
Nested bases appear as siblings in the multi-base registry; the longest-matching base root
wins for a given file path ( implied_context ).
