HybridStruct class

Value type that bridges with C-ABI struct layout.

Every @HybridStruct field crosses the FFI boundary on every call: primitive fields (int, double, bool) are copied by value at zero cost; String fields are heap-copied via strdup/free on both sides, adding ~100–500 ns per call — the cost grows with string length.

D4 guidance: If your struct carries one or more String fields that are frequently updated or compared, prefer @HybridRecord instead. Records are binary-encoded once and decoded lazily, making them significantly cheaper for text-heavy data (device names, error messages, config strings).

✅ Use @HybridStruct for hot-path data where all fields are numeric or boolean (sensor readings, camera frames, pixel coordinates). ✅ Use @HybridRecord for structured data with String fields or collections (device lists, configuration objects, API responses).
