Investigate potential NestJS SDK improvements based on native instrumentation hook

NestJS added a native instrumentation hook that can be used to get telemetry for framework internals produced by the DI container. We should look into if we can leverage this to improve our SDK.

Start by examining NestJS's native instrumentation hook and the existing NestJS SDK integration in this repository. Determine whether the hook can provide useful telemetry for dependency-injection container internals, then define the scope of any SDK improvement and how its behavior would be validated.
