Squidie.Runtime.Journal.Cancellation (squidie v0.1.2)

Journal-backed workflow cancellation.

Cancellation appends a terminal run fact to the run thread. Dispatch projections already overlay terminal run facts from run threads, so stale claims and later completions are fenced by the same durable source of truth. The configured queue selects the returned dispatch projection; cancellation itself is scoped by the globally unique run id.
