🔧 Fix testing infrastructure

✅ Fixed Issues:
- Import/export mismatches across all files
- Memory issues from auto-initialization
- Dynamic imports for Jest compatibility
- NODE_ENV=test detection to prevent auto-init
- Duplicate exports in multiple files

📊 Test Results:
- 11 tests passing (68% success rate)
- Core functionality verified
- No more memory crashes or heap exhaustion
- Tests actually run to completion

⚠️ Known Issues (5 tests still failing):
- Pipeline stages initialization
- SimpleLoader name property
- Validator methods
- StreamProcessor batching
- GraphQL dependencies

The test suite is now functional and can be extended.
