Pull request overview

This PR introduces a new registry-kit Go module providing Canton Registry utility onboarding/mint/supply verification helpers plus CCIP “token registry” utilities, and wires these utilities into existing CCIP integration tests.

Changes:

• Added registry-kit CLI + config/state management for devnet Registry onboarding, minting, and CCIP TokenAdminRegistry linking.
• Added registry/CCIP utility helpers (ACS discovery, choice-context building, disclosures, pool deploy/send/release helpers, package/DAR checks).
• Updated integration tests to consume registry-kit and added generated bindings / contract package metadata for Utility DARs.
