refactor: Simplify and consolidate GitHub Actions build workflow

This commit refactors the `build-desktop.yml` GitHub Actions workflow to streamline the build and release process.

-   **Permissions:** Adds `contents: write` permission to allow the `release` job to create a GitHub Release and upload artifacts.
-   **Build Matrix Simplification:** Consolidates the build matrix by removing redundant entries for each specific package format (`dmg`, `pkg`, `msi`, `deb`). Instead, it now uses a single entry per operating system (`macos`, `windows`, `linux`).
-   **Gradle Task Consolidation:** Replaces specific Gradle tasks like `packageDmg`, `packageMsi`, etc., with the more general `packageDistributionForCurrentOS`. This task automatically builds all configured native distribution formats for the running OS.
-   **Artifact Generation:** Adds `packageUberJarForCurrentOS` to the build step to ensure a standalone "fat" JAR is created for all platforms.
-   **Release Artifact Paths:** Updates the artifact upload and release attachment paths to correctly locate all generated packages (`.dmg`, `.pkg`, `.msi`, `.exe`, `.deb`, `.rpm`, `.jar`) from the unified build output directories.
