setup(App Skeleton): Configure WASM & Vite

[Ryan-Millard]

Summary

This pull request sets up the foundation for the Vite-based web application with WebAssembly (WASM) integration using Emscripten to handle C++ image processing.

Changes Made

1. Project Configuration

   • Added a project-level .gitignore to exclude build artifacts and environment-specific files.

2. Frontend Setup

   • Initialized a basic Vite application using React.

3. WASM Integration

   • Integrated WebAssembly via Emscripten to compile and expose C++ functions to JavaScript.
   • Added C++ source code under src/wasm.

4. Feature: Image Processing

   • Implemented a basic image file input in the UI.
   • Connected the image data to a C++ WASM module that performs colour inversion.

Notes

WASM build outputs are located in src/wasm/build/.

Ensure Emscripten is installed and configured properly to rebuild the WASM module as needed.
