Adds the executors module: shutdown() vs shutdownNow(), the graceful two-phase shutdown pattern, AutoCloseable/try-with-resources (JDK 19+), newVirtualThreadPerTaskExecutor() timing vs a bounded pool, and the submit()-without-get() lost-exception trap. 5 runnable demos, 1 JUnit correctness test class (23 tests), 6 captured output transcripts.

Running 5000 tasks that each sleep 50ms.

sample task thread: VirtualThread[#22]/runnable@ForkJoinPool-1-worker-1

newVirtualThreadPerTaskExecutor(): 5000/5000 tasks completed in 121ms
|
|
(121ms is close to the 50ms a single task takes - every task ran concurrently, nothing waited for a free worker)

sample task thread: Thread[#5027,pool-1-thread-1,5,main]

newFixedThreadPool(20): 5000/5000 tasks completed in 12556ms
|
|
(12556ms is roughly 250 rounds of 50ms each - only 20 tasks are ever running at once)
