rUv fde768f86d refactor(dragnes): move to standalone examples/dragnes/ app
Extract DrAgnes dermatology intelligence platform from ui/ruvocal/ into
a self-contained SvelteKit application under examples/dragnes/. Includes
all library modules, components, API routes, tests, deployment config,
PWA assets, and research documentation. Updated paths for standalone
routing (no /dragnes prefix), fixed static asset references, and
adjusted test imports.
