Parallel Step Execution With Join Semantics

A durable workflow execution engine for Elixir

Unique: Implements parallel execution as a workflow primitive with declarative join semantics, rather than requiring manual process spawning and result aggregation. The framework handles process lifecycle, error propagation, and result persistence, enabling developers to express parallelism as a control flow construct.

vs others: More declarative than manual Elixir process spawning and simpler than Temporal's activity parallelism (which requires custom activity implementations). Join semantics are explicit and queryable, unlike async/await patterns in imperative languages.
