feat(blackboard): add local Redis-backed coordination layer

Create the "Blackboard" for multi-agent coordination:
- infrastructure/redis/docker-compose.yml for local Redis deployment
- src/timmy/blackboard.py: Redis pub/sub + key-value store with in-memory fallback
- config.yaml: add blackboard configuration section
- tests/test_blackboard.py: smoke tests for KV and pub/sub

Agents can now write/read shared state and subscribe to events.
Deploy with: cd infrastructure/redis && docker-compose up -d

Closes #459

+# Local Redis Blackboard for Agent Coordination
+
+This directory contains the Redis deployment for the Timmy Home "Blackboard" — a
+shared coordination layer for multi-agent orchestration.

+## Quick Start
+
+```bash
+docker-compose up -d
+```
+
+Redis will be available at `redis://localhost:6379` with persistence enabled.

+## Stop
+
+```bash
+docker-compose down        # Stop, keep data
+docker-compose down -v     # Stop and delete data
