Describe the feature

Summary

Add support for TC39 Explicit Resource Management (ERM) proposal, enabling using and await using declarations in jiti.

Motivation

The Explicit Resource Management proposal (Stage 3, targeting ES2026) provides
a standardized way to manage resource cleanup using Symbol.dispose and Symbol.asyncDispose.

using file = openFile("data.txt");
// file is automatically disposed when exiting scope

Since jiti transpiles to CJS for execution, Node.js native ERM support is not available. Babel transformation is required.

Proposed Solution

Integrate @babel/plugin-transform-explicit-resource-management to transpile using/await using declarations into try-finally patterns.
