refactor: use ProcessHandle.current().pid() instead of RuntimeMXBean hack
(#3152)
Motivation:
PerfFlamesSupport.scala parses the PID from RuntimeMXBean.getName()
which returns "pid@hostname" — a pre-JDK 9 hack that depends on
an undocumented string format.
Modification:
Replace with ProcessHandle.current().pid() (JDK 9), the official
API for retrieving the current process ID.
Result:
Cleaner, more reliable PID retrieval without string parsing.
Tests:
sbt "multi-node-testkit/compile" — passed
