refactor(core): make closeRootScope async and await dispose

BREAKING CHANGE: closeRootScope is now async (returns Future<void> and must be awaited). This change improves resource lifecycle management by allowing asynchronous cleanup when disposing the root Scope. All usages of closeRootScope should be updated to use await.

- Change closeRootScope from void to Future<void> and add async keyword
- Await _rootScopefor correct async disposal
- Ensures proper disposal and better future extensibility for async resources

Closes #xxx (replace if issue exists)
