concurrency-interview: companion code for the Top 40 interview post

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.
