Add GitHub Actions release workflow

Add .github/workflows/release.yml to automate releases triggered by tag pushes (v*). The workflow creates a GitHub Release (named "Prasaran <tag>") with a brief body, then builds the Tauri app across a matrix (ubuntu-22.04, windows-latest, macOS aarch64 and x86_64). It sets up Node and Rust, installs Ubuntu native deps when needed, runs npm ci, and uses tauri-apps/tauri-action to produce platform installers/artifacts and attach them to the created release.
