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.
