refresh: stack al día (vello 0.7 / wgpu 27 / parley 0.6) + motor 3D voxel

Re-sincroniza las fuentes desde el monorepo (estaba en vello 0.5/wgpu 24 y con la
estructura vieja de eventloop) y suma el 3D:

- bump del workspace a vello 0.7 / wgpu 27 / parley 0.6, + accesskit 0.24 /
  accesskit_winit 0.33 / vello_hybrid 0.0.9.
- nuevos crates: llimphi-3d (voxels ray-march + mallas en un depth compartido,
  montable dentro de un View 2D vía set_viewport+scissor) y llimphi-voxel
  (world-gen, personajes, director de escenas) + shared/foreign-vox (puente .vox).
- README: sección "Not just 2D — a 3D voxel engine" + GIF (docs/llimphi_voxel.gif).
- excluido modules/allichay (arrastra deps fuera del alcance del front-door).
- cargo check --workspace: verde.

+//! `llimphi-widget-rating` — N estrellas clicables.
+//!
+//! Render: estrellas dibujadas a mano con `paint_with` (polígono de 10
+//! vértices). El caller pasa `value` (0..=max) y `max` (típicamente 5).
+//! Cada estrella es clickable: emite `on_change(idx + 1)`.
+//!
+//! Sober, no chillón: las estrellas inactivas son `border` (gris),
+//! las activas `accent`. Tamaño configurable, default 18 px.
