System, Display, Graphics, Sprite, Sound, File, JSON, Lua, Scoreboards, Network, Rect, SystemEvent, and AccessReply now live at module scope instead of being nested in the Playdate enum; consumers write System.log(...) instead of Playdate.System.log(...), and can qualify with the module name (PlayDate.System) on collision. The Playdate enum remains only as the raw C API bootstrap (initialize(with:), api, apiPointer), and Playdate.Error is renamed PlaydateError so no top-level type shadows Swift.Error. Breaking change for any existing consumers. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
