Concurrency Journeys

Two journeys on virtual threads and structured concurrency. Scope & Resource builds directly on VTask, so work them in order.

Where This Fits in the Bigger Picture

VTask is the deferred-effect type in the Core Types section of Foundations and the concurrent counterpart to IO. These journeys exercise the Monad instance for VTask and the structured-concurrency primitives that appear in any production version of the One Line, Six Layers anchor (where repo.find(id) is almost always async).
