v3.6.0 — Phase 5 Part 3: Redis Blackboard Backend

Body:

## What's New

### Redis Blackboard Backend
A Redis-backed `BlackboardBackend` for multi-process and multi-machine agent coordination — zero new production dependencies (user-supplied client).

```typescript
import { RedisBackend, SwarmOrchestrator } from 'network-ai';
import Redis from 'ioredis';

const backend = new RedisBackend(new Redis(), { keyPrefix: 'my-app:bb:' });
await backend.hydrate(); // load existing state from Redis

const orchestrator = new SwarmOrchestrator();
const board = orchestrator.getBlackboard('shared', { backend });

New Exports

Export	Description
RedisBackend	Redis-backed backend with write-through local cache
RedisClient	Interface — compatible with ioredis, node-redis v4+, or any mock
RedisPipeline	Interface for typed pipeline support
RedisBackendOptions	Options: keyPrefix, etc.

Key Methods

Method	Description
hydrate()	Load Redis keys into local cache on startup
flush()	Write all cache entries to Redis via a single pipeline
clearCache()	Reset local cache without deleting Redis keys
isReady	true after hydrate() completes
cacheSize	Number of entries in local cache

Testing

• 73 new tests (test-phase5c.ts) — in-process mock Redis client, no server required
• Covers: write/read, TTL expiry, write-through, hydrate, flush, round-trip, prefix isolation, export verification
• 625 total passing tests

No Breaking Changes

All existing backends (FileBackend, MemoryBackend) are unchanged. Omitting backend in getBlackboard() continues to use FileBackend by default.
