//! Integration tests for Futu connector
//!
//! **NOTE**: These tests are disabled because Futu uses TCP + Protocol Buffers,
//! not standard HTTP REST APIs. The connector is not functional without either:
//! 1. PyO3 bridge to Python SDK
//! 2. Native Rust Protocol Buffer client
//! 3. External REST adapter service
//!
//! See research/RECOMMENDATIONS.md for implementation options.
