A ClassLoader that supports dynamic addition of parent classloaders at runtime.

Key features:

• Initializes without a parent classloader

• Allows adding multiple parent classloaders dynamically

• Designed for custom class resolution strategies

Primary usage:

1. Implement and return in org.jetbrains.kotlinx.jupyter.api.KernelRunMode.createIntermediaryClassLoader

2. Access via org.jetbrains.kotlinx.jupyter.api.Notebook.intermediateClassLoader

3. Cast to ModifiableParentsClassLoader and add required parent classloaders as needed

Typical use case: Loading IntelliJ plugins' classes in embedded mode.
