Sync version properties and README badges with streambuffer reference setup

Add jqwik.version, archunit.version, spotbugs.version, fb-contrib.version,
findsecbugs.version properties; reference them from dependency/plugin
declarations instead of hardcoding.

Add jcstress, Lincheck, vmlens badges to README Build section; update JMH
badge to use canonical openjdk.org link and hex color #25A162.
