Pull request overview

This PR adds support for using item proxies in Ruby case statements by implementing the === (case equality) operator. The implementation follows the same pattern as the existing == operator to ensure proxied items can be properly compared in case/when constructs.

Changes:

• Implemented the === operator for item proxies to delegate to underlying objects
• Added tests to verify the case equality operator works correctly with item proxies
