Create Rust with Dart FFI implementation (Rust for image processing, Flutter for UI)

[enzoftware]

Task Overview:

• Implement a new architecture using Rust for image processing logic, exposing functions via FFI.
• Integrate with a Flutter front-end (Dart) for cross-platform UI.

Detailed Steps:

1. Design the Rust library exposing image processing functions (e.g., filters, transformations) via FFI.
2. Set up the FFI interface using #[no_mangle] functions and C-compatible types.
3. Create a Dart wrapper using dart:ffi to bind to Rust functions.
4. Develop a Flutter UI that calls Rust via FFI for processing images.
5. Write integration and unit tests to ensure reliability and performance.
6. Document architecture, build steps, and usage in the README and code comments.
7. Compare performance and capabilities with the existing C and Android implementations.
8. Add automation for building and publishing the Rust library for multiple platforms.
