Enhance CI workflow for multi-platform packaging

Improve the GitHub Actions CI workflow: package Windows exe and SFML DLLs from vcpkg into a zip, add installation of Linux system deps for SFML, and pick the correct macOS vcpkg triplet (arm64 vs x64) and propagate it to CMake. Make artifact handling more robust in the release job by checking out, downloading artifacts conditionally (continue-on-error), and uploading only available artifacts via a scripted curl uploader. Also include minor cleanup: rename/clarify some step names, fix path separators and whitespace, and make vcpkg install step naming consistent.
