CMDx 2.0.1 lands a handful of focused improvements to the service-object runtime, mostly around fault handling, callback semantics, and observability.

What’s new:

• Fault#cause is now linked — raised faults preserve the underlying exception, so error trackers and stack traces point at the real origin instead of dead-ending at the framework.
• Context lookup perf — Context#method_missing resolution order was simplified, trimming allocations on a very hot path.
• I18n for full_messages — validation error full_messages now attempt translation, with a clean fallback when no key exists.
• New :task_rolled_back telemetry event — workflows emit a dedicated event on rollback, making it easy to alert/dashboard on compensating actions.
• Cleaner callback ordering — around_execution now wraps only Task#work (and any #rollback). before_validation runs before the around-block; after_execution runs after it. Previously both were nested inside the around-block, which muddied timing/logging.
