网络架构:
- iot-platform: host -> bridge (新增 -p 8887:8887 端口映射)
- taos-explorer: bridge (新增 /mnt/taos-explorer-data 数据持久化)
- tdengine-operator: 保持 host 网络

配置更新:
- TDengine URL: 127.0.0.1 -> 172.21.185.173 (宿主机内网 IP)
- Redis host: localhost -> ${REDIS_HOST:localhost} 环境变量
- taos.cfg fqdn: 127.0.0.1 -> 172.21.185.173
- explorer.toml cluster: localhost -> 172.21.185.173

部署脚本:
- REMOTE_DIR: /opt/iot-platform -> /mnt/iot-platform
- 日志目录: /opt/iot-platform/logs -> /mnt/iot-platform/logs
- 去掉自动回滚逻辑，保留容器用于排查
- 新增 -p 8887:8887 端口映射

新增服务器配置文件到仓库:
- deploy/Dockerfile
- deploy/start-container.sh
- deploy/config/taos.cfg
- deploy/config/explorer.toml
- deploy/config/tdengine-explorer.conf
- .env (移除 .gitignore 忽略)

- Delete 6 legacy RuoYi modules (ruoyi-admin/framework/system/common/quartz/generator)
- Create new iot-platform Spring Boot 2.5.15 module with all IoT business
- Migrate 5 MQTT consumers, VehicleSyncTask, 14 services, 15 domains/mappers
- P0 security fixes:
  - Replace string-concat SQL with field whitelist + escapeValue in TDengineService, DynamicSqlProvider, TDegnineAlarm
  - Externalize hardcoded MQTT/TDengine credentials to application.yml via IotProperties
  - Fix thread-unsafe static shared Connection/Statement in TDegnineAlarm (use per-method connections)
- Logging normalization: replace 148 System.out/err.println with SLF4J, add logback-spring.xml (100MB rolling, 30d retention)
- Dead code cleanup: NumericIdGenerator (238→65 lines), merge TDengineConnecting into TDengineService
- Verified: mvn clean package passes, app boots with all 5 MQTT consumers

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
