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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
