fix: allow cancelled flows to be retried Remove CANCELLED from FROM_STATES in EnforceCancellingToCancelledTransition. This rule should only block transitions FROM CANCELLING, not CANCELLED. The rule name, docstring, and error message all reference "cancelling" states, but the implementation incorrectly included CANCELLED, preventing retries.
