Add Hugo website and rewrite docs to match current engine

New Hugo site in website/ with prosperon.dev theme (blue/gold/castle
aesthetic), docs sidebar navigation, and content pages. Rewrote all
doc files to align with the actual codebase: compositor+film2d
rendering, use() modules (no global prosperon object), Pit language,
script+JSON entity model. Added entities.md, front matter to all
70+ API docs, and updated API index for current module architecture.
