Subscriptions — long-running sources of events that the runtime starts and stops as the model changes.
An app declares its active subscriptions via the optional subs/1
callback. The runtime diffs the returned list against what's currently
running on each render: new entries get started, removed entries get
stopped. The list is keyed by structural identity, so the same sub spec
returned twice produces only one running process.
v0.1 provides Sub.interval/2. Richer kinds (pubsub, file watchers,
signal handlers, websockets) arrive alongside the full Cmd executor.
