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
+
+Review checkpoint after implementing both WebSocket adapters. These are the first fan-out adapter (server) and the first subscription-control adapter (client), so they establish patterns that the Worker and Iroh adapters will follow.
+
+Verify:
+- Subscription control protocol (`__subscribe`/`__unsubscribe`) is correctly implemented in both client and server
+- Topic-based fan-out works end-to-end: client subscribes → server tracks → server fans out
+- Backpressure protection works correctly
+- Error handling matches the architecture spec
+- Build, type-check, and test suite all pass
+
+## Acceptance Criteria
+
+- [ ] `npm run build` passes cleanly
+- [ ] `npm run lint` passes
+- [ ] `npm test` passes with all core + Redis + WebSocket tests
+- [ ] WebSocket client subscription forwarding matches ADR-003
+- [ ] WebSocket server fan-out and subscription tracking matches architecture spec
+- [ ] No unnecessary comments in source (project convention)
+- [ ] License headers present where needed
