## DBFlute Code Generation

DBFlute generates type-safe data access code for OpenSearch indices:

```bash
mvn dbflute:freegen
```

Generated code:

- **Special cases**: Kurdish uses `fess_label_ckb_IQ.properties`

## Step-by-Step Guide

### 1. Create Language Resource Files

Copy the base English files as templates:

```bash
cd src/main/resources

# Copy label file (~1,056 translation entries)
cp fess_label_en.properties fess_label_[your_locale].properties

# Copy message file (~200 translation entries)
