Pull request overview

This PR removes the remaining deprecated elements from the public domain annotations (pinning filter and legacy “difficulty/strength/nullable” sorting attributes) and updates the internal descriptor processing plus test domains to use the non-deprecated replacement APIs.

Changes:

• Removed deprecated public API elements: PinningFilter, PlanningEntity.pinningFilter, PlanningVariable.nullable, and legacy difficulty/strength sorting attributes.
• Updated EntityDescriptor/BasicVariableDescriptor to stop interpreting deprecated annotation attributes and to rely on the modern comparator* and allowsUnassigned properties.
• Refactored/trimmed test domains and tests that exercised the deprecated APIs (including removing entire legacy test models).
