- Comprehensive Javadoc on public APIs

## Test Conventions

- Test class names end with `Test`
- Test methods start with `test_` prefix
- Tests use `## Arrange ##`, `## Act ##`, `## Assert ##` comments
- Some integration tests require network access

## Important Notes for AI Assistants

1. **Resource Management**: Always use try-with-resources with `CurlResponse`.
