Description
Scripts/Modules running in the context created with vm.createContext can not access various Node.js built-in apis/modules like URL, node:assert, node:http, etc. This makes it cumbersome to create a disposable context for use cases like hot-module-reload to run existing node.js apps.
We can provide a built-in API to create a context (or a new NodeRealm for compatibility) with full-fledged Node.js built-in modules support. It allows object exchanges between realms and shares the same loop with the main context.
, similar to the existing vm.context.

Research direction
Start by reading the existing vm.createContext API and the issue's references to Node.js built-in modules, including URL, node:assert, and node:http. Define how a new context or NodeRealm would provide built-in module access, object exchange between realms, and a shared event loop; the issue does not name implementation files or tests.
