feat: 添加回路名称字段并实现元数据缓存查询

在 RCU 事件处理中新增回路名称（loop_name）字段，用于标识具体设备回路。
- 在 rcu_action_events 表中添加 loop_name 字段
- 新增项目元数据缓存模块，每日从 temporary_project 表刷新房间与回路信息
- 处理消息时，根据 device_id、dev_addr 等字段查询缓存获取回路名称
- 若缓存未命中，则根据设备类型规则生成兜底名称
- 更新环境变量、文档及测试用例以适配新功能

+6. 入库前特殊操作
+ - 定期从temporary_project表中读取数据并保存到`内存`中（以全局变量的形式），每天凌晨1点从数据库更新一次。
+ - 每条数据写库之前，需要根据项目ID从内存中读取项目信息。
+ - 我需要在现有数据表`rcu_action_events`里，添加一个字段：`loop_name`，用于存储回路名称。
+ - 查询`loop_name`的方法是：
+  - 根据要插入的数据中的`device_id`在`rooms`表中找出对应的房间 -> 得到 `room_type_id`。
+  - 根据 `room_type_id` 和 `loop_address` 在 `loops` 表中查找对应的 `loop_name`。
+  - `loop_address` 的生成规则：将数据的 `dev_type`、`dev_addr`、`dev_loop` 分别转换为 3 位字符串（不足前方补 0），然后拼接。
+    - 例如：`dev_type=1, dev_addr=23, dev_loop=12` -> `001` + `023` + `012` -> `001023012`。
+  - **兜底逻辑**：如果根据上述规则在 `loops` 缓存中未找到对应的 `loop_name`，则使用 `dev_type` 对应的设备名称（配置在 `ACTION_TYPE_DEV_TYPE_RULES` 中）默认名称。
+    - 格式：`[dev_type名称+'-'+dev_addr+'-'+dev_loop]`
+    - 例如：`dev_type=35` (名称: TimeCtrl), `addr=14`, `loop=21` -> `[35TimeCtrl-14-21]`
+  - 最后将找到的或生成的 `loop_name` 写入 `rcu_action_events` 表。
+    - 注意，所有查库操作都要通过内存缓存来实现。

+# Feature: Loop Name Enrichment
+
+**Status**: Proposed
+**Date**: 2026-02-02
+
+## Summary
+Enrich incoming RCU action events with `loop_name` by looking up metadata from `temporary_project` tables. This allows easier identification of specific device loops (e.g., "Main Chandelier") in the event log.
+
+## Requirements
+1.  **Cache Mechanism**: 
+    - Load `rooms` and `loops` data from `temporary_project` schema into memory.
+    - Refresh cache daily at 1:00 AM.
+2.  **Enrichment**:
+    - For each incoming event, look up `loop_name` using `device_id` and `dev_addr`.
+    - `device_id` -> `room_type_id` (via `rooms` table).
+    - `room_type_id` + `dev_addr` -> `loop_name` (via `loops` table).
+3.  **Storage**:
+    - Store `loop_name` in `rcu_action_events` table.
+
+## Ambiguity Resolution
+- The requirement mentioned matching `dev_type` to find the loop. However, standard RCU addressing uses `dev_addr` (and `dev_loop`). We assume `loops.loop_address` corresponds to the packet's `dev_addr` (converted to string).
+- We will attempt to match `dev_addr` against `loop_address`.
+
+## Schema Changes
+- **Table**: `rcu_action.rcu_action_events`
+- **Column**: `loop_name` (VARCHAR(255), Nullable)
+
+## Implementation Plan
+1.  **Database**: Update `init_db.sql` and `databaseManager.js`.
+2.  **Cache**: Create `src/cache/projectMetadata.js`.
+3.  **Processor**: Integrate cache lookup in `src/processor/index.js`.
+4.  **Lifecycle**: Initialize cache in `src/index.js`.

 - **Output**: PostgreSQL Table (`rcu_action_events`)
 
+## Features
+- **Loop Name Enrichment**: Enriches event data with `loop_name` by matching `device_id` and `dev_addr` against metadata cached from `temporary_project` tables (refreshed daily).
