- deploy/README.md: systemd → Podman 容器化部署
- CLAUDE.md: 更新部署命令、TDengine URL、.env 加载方式

- 停止/启动 systemd 服务 → 停止/启动 Podman 容器
- 部署时自动构建容器镜像
- 回滚逻辑同步改为容器方式

When --no-rollback is set, the script keeps the new version on the
server even if health check fails, making it possible to inspect
startup logs via journalctl to diagnose the issue.

Security (P0):
- Remove hardcoded MySQL password from SysrealtimeService
- Add table name whitelist validation (regex + length limit)
- Validate ${tableName} in SysrealtimeMapper.xml
- Externalize all credentials to .env file
- Fix unbounded thread pools in MQTT consumers
- Fix mysqlWritePool leak in MqttFaultConsumer

Quality (P1):
- Extract AbstractMqttConsumer base class (-500+ duplicate lines)
- Refactor VehicleSyncTask: SCAN instead of KEYS, batch ops,
  RestTemplate timeout, loop-invariant extraction
- Add unit tests (RedisKeys, SysrealtimeService, MqttConsumer)

Architecture (P2):
- Add Spring Boot Actuator (/actuator/health)
- Create RedisKeys constants class for key namespace
- Add .env.example and start.sh for local development

Deployment:
- Add systemd service (iot-platform.service)
- Add deploy.sh with build, upload, backup, health check, rollback
- Add setup-server.sh for server initialization
- Add health-check.sh (Actuator + TCP port fallback)

Docs:
- Update CLAUDE.md for standalone iot-platform architecture
- Update README.md with build/deploy instructions
- Add deploy/README.md
