Analyzer java-runtime-overview

# Name

java-runtime-overview - Java Runtime Event Overview

This analyzer provides a quick overview of several JVM runtime signals in one result. It reports safepoint pauses, GC pauses, runtime allocation slow-path events, lock/park waits, and Java thread run/exit events in a bar chart. Separate histograms show pause durations, futex-backed lock/park wait durations, and slow-path allocation sizes, so you can see both event counts and long tails without starting several analyzers first.
