Motivation

This PR resolves several issues in the Engine V2 provider related to template delta handling and reference evaluation. Specifically, it addresses:

• Misinterpretation of deltas in templates where property definitions are empty or missing
• Faulty comparison logic in preprocessor delta conditions, where the absence of a condition was incorrectly treated as a match
• Limited handling of reference evaluation when a physical ID changes during updates
• Additional minor issues and inconsistencies

Changes

• Fixed misinterpretation of deltas in templates with empty/missing properties
• Corrected logic for comparing preprocessor delta conditions
• Improved handling of Ref evaluation across physical ID changes
• Fixed the lack of describe and execution pruning for unchanged resources
• Addressed various minor issues
