What does this PR do?
Implements JVM HotSwap via a Java Agent to enable in-place class redefinition while preserving static field values.
Fixes #119.
Details
The root issue is that
URLClassLoadernatively caches already-loaded classes, preventing the JVM from picking up updated bytecodes when a variable is redeclared. The solution leveragesInstrumentation.redefineClasses()to perform in-place (HotSwap) class redefinition, mirroring how thejshelltool redefines classes through JDI.Testing
Added a test to cover the detected regression.
