CoroutineDriver

Run the given tasks concurrently and return an array containing the results.

Each task runs in its own coroutine with the parent's context propagated. Results are keyed to match the input array. If any task throws, the exception is re-thrown after all tasks complete.

Start the given tasks concurrently in the background after the current task has finished.

Uses Hypervel's lifecycle-aware defer system so tasks execute at the appropriate lifecycle point (after HTTP response, after command completion). Each deferred task runs in its own coroutine with context propagated.
