Adds the concurrency-interview module: a real race condition with its actual lost-update count, why volatile alone doesn't fix it, a real JVM-detected deadlock (ThreadMXBean.findDeadlockedThreads()) with the fix, and ScopedValue's exact child-thread inheritance rules (finalized in JDK 25 via JEP 506, demonstrated against StructuredTaskScope, still preview per JEP 505/525). 4 runnable demos, 1 JUnit test class (9 tests), 5 captured output transcripts.
