Fix CI workflow

- Added a step to upload frontend build artifacts after the build process. - Included a step to download the frontend assets in the backend build job, ensuring the backend has access to the latest frontend build.
Update package version to 1.4.0 and switch Svelte adapter to static

 ## Self-Hosting

+## Desktop Application
+
+You can build the desktop application for your platform using Wails:

 ```sh
-podman run -p 3000:3000 git.quad4.io/quad4-software/linking-tool
+make desktop-build
 ```

+The binary will be located in `bin/`.

-## Docker
-
-Uses Chainguard Images which are rootless and very minimal images.
+The project uses a Makefile for all common tasks:

 ```sh
-docker build -t quad4-linking-tool .
-docker run -p 3000:3000 quad4-linking-tool
+make dev      # Run development servers (Go & SvelteKit)
+make build    # Build the single binary web server
+make help     # List all available targets
 ```

+### Docker Build & Artifact Extraction
+
+If you don't have the development environment (Go, Node, Wails) installed locally, you can build and extract binaries using Docker:
+
+```sh
+make docker-builder
+```
+
+This will build the server and desktop application inside a container and copy the resulting binaries to the `bin/` directory on your host machine.
