v0.1.0-alpha.6

Added

• Saga compensation callbacks with compensate: SomeAction, executed in reverse completion order after downstream terminal failure with persisted recovery history.
• Failure-route recovery markers with recovery: :compensation | :undo on error transitions, plus :compensation_routed and :undo_routed audit events.
• Local repo transaction groups for custom steps through transaction: :repo, wrapping the step action in the configured repo transaction.
• Minimal host app examples and smoke coverage for saga checkout, gateway credit compensation routing, and local ledger transaction commit/rollback.

Changed

• Workflow authoring, operations, README, and host app documentation now distinguish saga rollback, same-step failure routing, undo, and local repo transaction boundaries.
• Runtime failure and compensation paths now preserve more recovery metadata for inspection and explainability.

Fixed

• Hardened compensation outcome handling and terminal target serialization for failure recovery routes.
• Nested exception structs in step error details no longer crash error normalization.

Notes

• This remains an alpha release. transaction: :repo is a local host repo boundary only; it is not a distributed transaction across durable workflow progress, Oban dispatch, external systems, or compensation callbacks.
