Structured Concurrency is More Than ShutdownOnFailure

Since Java 21, structured concurrency has been introduced as a preview feature to manage parallel sub-tasks within a given scope. While common use cases focus on `ShutdownOnSuccess` and `ShutdownOnFailure`, the 'Virtually' project extends capabilities with `EnhancedTaskScope`. This includes throttling to limit simultaneous tasks, circuit breaker mechanisms, default values upon task failure, critical task prioritization, and efficient list conversion using structured concurrency. These enhancements help manage high load and failure scenarios more effectively, leveraging the power of Java's virtual threads.
