feat: llimphi standalone — framework UI soberano extraído del monorepo

Motor gráfico Llimphi como workspace independiente: bucle Elm
(input→update→view→layout→raster→present) sobre wgpu+vello+taffy+parley.
Núcleo (hal/raster/layout/text/ui/theme/surface/motion/icons) + ~40 widgets
+ módulos, sin dependencias al resto del monorepo. cargo check --workspace
pasa (64 crates). Puerta de entrada: cargo run -p llimphi-ui --example counter.
