Replace the Swift site generator with a Ruby and Phlex implementation. Loads site and projects from TOML, derive site metadata from posts. Migrate from make to bake and add standardrb and code coverage tasks. Update CI and docs to match the new workflow, and remove unused assets/dependencies plus obsolete tooling.
