Publish safely through a chosen channel

Implement static List<String> publishViaQueue(): 1. A worker virtual thread: builds List.of("payload-1", "payload-2"), then puts it on a SynchronousQueue<List<String>>. 2. The main path take()s it and returns the list. 3. Also implement static boolean queueCarriesHappensBefore() returning true — documenting that BlockingQueue operations establish hb between producer and consumer. 4. Implement static List<String> tornRead() that returns a list published through a PLAIN static field, slept 1ms, then re-read — this is intentionally NOT guaranteed (the test only checks the method exists and returns some list; the LESSON explains why it is unsafe).
