Add actor-owned contextual process provisioning, descriptor bootstrap, scoped namespace operations, Python bindings, Myelin orchestration, and adversarial end-to-end coverage. Remove the superseded job runner, pipeline APIs, images, entrypoints, and specifications.
Add durable namespace control, Iroh-backed source transfer, session-independent publication lifetime, and wire managed Myelin jobs and bindings through the reusable data-plane API.
