feat(processor): 添加循环名称自动生成的配置开关

新增环境变量 ENABLE_LOOP_NAME_AUTO_GENERATION 用于控制当缓存未命中时是否自动生成循环名称。当设置为 false 时，系统将不再生成 [类型-地址-回路] 格式的备用名称，而是直接返回 null。更新了配置文件、处理器逻辑并添加了相应的单元测试。

+# Feature: Feature Toggle Loop Name Generation
+
+**Status**: Implemented
+**Date**: 2026-02-03
+
+## Summary
+Add a configuration switch to control the fallback behavior for `loop_name` generation. Currently, when cache lookup fails, the system auto-generates a name using the format `[Type-Addr-Loop]`. This change allows users to enable or disable this fallback behavior via an environment variable.
+
+## Requirements
+1.  **Configuration**: 
+    - Add `ENABLE_LOOP_NAME_AUTO_GENERATION` to environment variables.
+    - Default behavior should match existing logic (enable generation) if not specified, but user requested explicit control.
+    - If `true`: Perform concatenation `[dev_type名称+'-'+dev_addr+'-'+dev_loop]`.
+    - If `false`: Do not generate name, leave `loop_name` as null (or whatever default is appropriate, likely null).
+
+2.  **Processor Logic**:
+    - In `getLoopNameWithFallback`, check the configuration flag before applying the fallback generation logic.
+
+## Implementation Plan
+1.  **Config**: Update `src/config/config.js` to parse `ENABLE_LOOP_NAME_AUTO_GENERATION`.
+2.  **Env**: Update `.env` and `.env.example`.
+3.  **Processor**: Update `src/processor/index.js` to respect the flag.

+# Summary of Changes: Loop Name Features
+
+**Date**: 2026-02-03
+**Status**: Archived
+
+## Overview
+This archive contains the specifications and proposals for the Loop Name Enrichment and Auto-Generation features. These features enhance the RCU Action Server by enriching event data with descriptive loop names derived from project metadata or fallback generation logic.
+
+## Included Changes
+
+### 1. [Feature: Loop Name Enrichment](./feature-loop-name-enrichment.md)
+- **Goal**: Enrich `rcu_action_events` with `loop_name` by looking up cached metadata from `temporary_project` tables.
+- **Key Components**:
+  - `ProjectMetadataCache`: Loads rooms and loops data daily.
+  - `loop_name` column added to `rcu_action_events` table.
+  - Processor logic updated to perform lookup.
+
+### 2. [Feature: Feature Toggle Loop Name Generation](./feature-toggle-loop-name-generation.md)
+- **Goal**: Provide a configuration switch to control the fallback behavior when cache lookup fails.
+- **Key Components**:
+  - `ENABLE_LOOP_NAME_AUTO_GENERATION` env var.
+  - Logic to generate `[Type-Addr-Loop]` format only if enabled.
+  - Default behavior is `true` (enabled).
+
+## Implementation Status
+- All proposed features have been implemented and verified via unit tests.
+- Configuration variables are documented in `.env.example`.
