- Introduced Aggregator.sol for Chainlink-compatible oracle functionality, including round-based updates and access control. - Added OracleWithCCIP.sol to extend Aggregator with CCIP cross-chain messaging capabilities. - Created .gitmodules to include OpenZeppelin contracts as a submodule. - Developed a comprehensive deployment guide in NEXT_STEPS_COMPLETE_GUIDE.md for Phase 2 and smart contract deployment. - Implemented Vite configuration for the orchestration portal, supporting both Vue and React frameworks. - Added server-side logic for the Multi-Cloud Orchestration Portal, including API endpoints for environment management and monitoring. - Created scripts for resource import and usage validation across non-US regions. - Added tests for CCIP error handling and integration to ensure robust functionality. - Included various new files and directories for the orchestration portal and deployment scripts.
