refactor(store-sync): use config namespaces for tables

+---
+
+Refactored `syncToRecs` and `syncToZustand` to use tables from config namespaces output. This is a precursor for supporting multiple namespaces.
+
+Note for library authors: If you were using `createStorageAdapter` from `@latticexyz/store-sync/recs`, this helper no longer appends MUD's built-in tables from Store and World packages. This behavior was moved into `syncToRecs` for consistency with `syncToZustand` and makes `createStorageAdapter` less opinionated.
+
+You can achieve the previous behavior with:
+
+```diff
+ import { createStorageAdapter } from "@latticexyz/store-sync/recs";
++import { mudTables } from "@latticexyz/store-sync";
+
+ createStorageAdapter({
+-  tables,
++  tables: { ...tables, ...mudTables },
+   ...
+ });
+```
