Caution Review failedThe pull request is closed. 📝 WalkthroughWalkthroughThis PR comprehensively enhances the Aether runtime with artifact storage and repository management, autonomous rollback orchestration, refined alerting infrastructure, and asynchronous Promise-based slice invocation patterns. It introduces new configuration types (SliceConfig, RollbackConfig, AlertConfig), artifact deployment tracking, failure event propagation, endpoint failover with exclusion, and integrated metrics collection.
