Decompose architecture into atomic, dependency-ordered tasks

19 tasks covering core testing, Redis hardening, WebSocket client/server
adapters, Worker adapter, and final review gates. Iroh adapters are tracked
as a deferred placeholder blocked on the @alkdev/iroh fork.

Phases: core validation → Redis hardening → review gate → WebSocket
adapters → review gate → Worker adapter → review gate → final validation.

+
+## Description
+
+Test that `createPubSub` works correctly when configured with the Redis event target. This is an integration test that verifies the core factory and the adapter work together:
+
+```ts
+const pubsub = createPubSub<MyEventMap>({
+  eventTarget: createRedisEventTarget({ publishClient, subscribeClient }),
+});
+```
+
+This tests the full round-trip: publish through createPubSub → dispatch through Redis → receive on the other side.
+
+## Acceptance Criteria
+
+- [ ] Integration test: publish via `createPubSub` + Redis event target
+- [ ] Integration test: subscribe via `createPubSub` + Redis event target
+- [ ] Integration test: full envelope round-trip (type, id, payload)
+- [ ] Integration test: topic scoping works with `type:id` through Redis
+- [ ] Integration test: channel prefix is correctly applied when configured
