Pull request overview

This PR adds a fail-fast validation check for deep cloning configuration. The check ensures that if a planning variable field is marked with @DeepPlanningClone, its type must also be deep-cloneable. This prevents runtime issues where the solver might fail to recognize that an assigned value belongs to a value range.

Changes:

• Added fail-fast validation to detect invalid deep cloning configuration for planning variables
• Created test domain classes to demonstrate the invalid scenario
• Added test case to verify the error is thrown with appropriate messaging
