feat(scripts/dev): extend native detection for both C++ and Rust libraries

Update detect-native.go to detect and report both C++ and Rust native libs:

- Split library detection into C++ (native/build/) and Rust (native_rust/target/release/) sections

- Display separate '=== C++ Native Libraries ===' and '=== Rust Native Libraries ===' headers

- Check for both .so and .dylib extensions for each platform

- Update help text to show 'make native-build' for C++ and 'make rust-build' for Rust

- Show benchmark file availability for both implementations
