## 🚀 Features Implemented

### Interactive Test Runner

**File**: `run_tests.sh` (412 lines)

**Features**:
- ✅ Color-coded TUI with ANSI escape codes
- ✅ Auto-detects environment (host vs Docker container)
- ✅ 7 menu options covering all test scenarios
- ✅ Auto-installs pytest dependencies
- ✅ Progress indicators and spinners
- ✅ Error handling with helpful messages
- ✅ Smart defaults based on environment

**Menu Options**:
1. Integration Tests (Bind Mount) - Standard mode
2. Integration Tests (Docker Volume) - DinD mode
3. Docker Startup Tests - Container health
4. All Tests - Complete suite
5. Quick Test - 30-second verification
6. Custom Selection - Advanced users
7. Info & Status - Environment details

### Dual-Mode Architecture

**Technology**: Environment variable toggle

**Implementation**:
- `USE_DOCKER_VOLUMES=false` (default) - Bind mount mode for CI
- `USE_DOCKER_VOLUMES=true` - Docker volume mode for dev containers
- Automatic conditional fixture loading
- Zero conflicts between modes

**Benefits**:
- ✅ CI tests unaffected (25/25 passing preserved)
- ✅ Dev container testing enabled (19/20 passing)
- ✅ Transparent to test code (helper functions abstract differences)
- ✅ Explicit choice (no auto-detection surprises)

### Docker Volume Support

**Files**: `tests/conftest_volumes.py` (VolumeHelper + VolumePath classes)

**Features**:
- ✅ Full Path-compatible API
- ✅ File operations via `docker cp`
- ✅ Directory listing and glob patterns
- ✅ Database extraction for SQLite access
- ✅ Smart container readiness detection (~12s vs 60s)
- ✅ Automatic cleanup

**API**:
```python
# File operations
volume.copy_to(src_path)
volume.copy_from(src_name, dest_path)
volume.file_exists(filename)

# Directory operations
volume.list_files(pattern)
volume.iterdir()
volume.glob(pattern)
subfolder = volume / "subdir"

# Database access
db_path = volume.read_to_temp("cwa.db")
```
