UI5 Middleware: Serve Local Framework

This UI5 middleware, `ui5-middleware-serveframework`, integrates with the UI5 tooling to provide a local serving mechanism for the OpenUI5 or SAPUI5 framework. It automatically builds and caches the specified UI5 framework version (as defined in the project's `ui5.yaml`) into a local directory (`~/.ui5/ui5-middleware-serveframework` by default). Subsequent requests for the same UI5 version are then served directly from this local cache, significantly improving development server startup times and ensuring consistent, offline-capable environments by leveraging preload files and direct static file access. The current stable version, 3.7.1 (as of the last search results), indicates a healthy, community-driven project with regular updates. Its key differentiator is the ability to use a fully local, pre-built UI5 framework, offering benefits over relying on remote CDN sources or repeated on-the-fly compilation.
