+feat: export RpcClient and connect from main entry point
+
+Re-export `RpcClient`, `connect`, and related types from the main entry point for better compatibility with bundlers (Cocos Creator, Vite, etc.) that may have issues with subpath exports.
+
+```typescript
+// Now works in all environments:
+import { rpc, RpcClient, connect } from '@esengine/rpc';
+
+// Subpath import still supported:
+import { RpcClient } from '@esengine/rpc/client';
+```
