Subject: [PATCH 2/2] docs: note multi-file modules need the Kin CLI

Playground is single-buffer; koresha/emerera_gukoresha require kin run
on disk. Point to examples/importing and Modules docs.

+
+## Notes
+
+- The playground runs a **single buffer** in the browser.
+- Multi-file modules (`koresha "…" nka alias` / `emerera_gukoresha`) need the **CLI**
+  (`kin run entry.kin`) so files can be loaded from disk. See `examples/importing/`
+  in the language repo and the [Modules](https://kinlang.vercel.app/docs/language-structure/Modules) docs.
+- Typed samples and OOP/`ubwoko` printing are aligned with recent Kin releases when
+  `@kin-lang/kin` is updated in this package.
