feat(config): 添加配置管理和MQTT模拟服务功能

- 实现了应用配置的数据类结构(MqttConfig, TmsConfig, AppConfig)
- 创建了配置加载和解析功能，支持从YAML文件读取配置
- 添加了TDengine数据库配置和连接池管理
- 实现了MQTT客户端依赖注入和服务构建
- 创建了钻孔实时数据的ORM映射和SQL构建功能
- 实现了TDengine Writer用于数据写入超级表
- 添加了MQTT模拟服务，支持发布、订阅和数据转发功能
- 创建了随机数据发送器用于测试
- 实现了消息持久化到本地文件功能
- 配置了数据库连接池和SQL执行功能

+# MQTT Mock Service
+
+Simulates a service that:
+- Subscribes to the ingest topic (server -> broker)
+- Writes received messages to a local file (JSONL)
+- Writes received messages to TDengine (super table)
+- Forwards messages to another topic for downstream subscribers
+- Optionally sends ack messages
+
+Also includes:
+- A random data sender (every 3 seconds by default)
+- A simple subscriber that prints incoming payloads
+
+## Setup
+```
+python -m venv .venv
+.\.venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+## Run (service mode)
+```
+python mqtt_mock.py --config config.yaml --mode listen
+```
+
+When TDengine config exists in `config.yaml`, each message on `pub-topic` is inserted into:
+- Super table: `drilling_realtime_st`
+- Sub table: auto-generated as `drilling_realtime_<device_code>`
+- Tag value: fixed `device_code` from config (`GJ-304-0088`)
+
+## Run (also publish test data)
+```
+python mqtt_mock.py --config config.yaml --mode both --interval 2
+```
+
+## Run random sender (3s interval)
+```
+python mqtt_sender.py --config config.yaml --interval 3
+```
+
+## Run subscriber
+```
+python mqtt_subscriber.py --config config.yaml
+```
+
+## Payload format (server -> broker)
+```
