Workflow Cancellation With Cascading Cleanup

A durable workflow execution engine for Elixir

Unique: Implements workflow cancellation as a first-class operation with automatic compensation execution, rather than as a simple state flag. Cancellation is resumable and fully observable, enabling graceful shutdown of workflows with complex resource cleanup.

vs others: More sophisticated than simple workflow termination and simpler than Temporal's cancellation (which requires custom activity implementations). Cancellation automatically triggers compensations without explicit cleanup logic.
