Upgrade prototype to ConfigKit 0.4.0

examples/library-adoption/README.md

@@ -4,6 +4,9 @@ This experimental executable exercises Audita's ConfigKit/PromptKit boundary. It
 is a standalone nested Go module, not a production Audita command. Its configuration
 and profile files are accepted by this prototype only. Design decisions, limitations,
 and migration status belong to the [findings](../../docs/roadmap/library-boundary-findings.md).
+The current prototype pins ConfigKit v0.4.0; the original v0.3.1 results remain
+historical evidence in the findings. Selected overlays are not wired into this
+executable yet.
