feat(v0.5.0): visualizador de audio animado

- VisualizadorAudio: 24 barras verticales con movimiento orgánico
  (senos compuestos con fases aleatorias). Activo=animación fluida,
  parado=decaimiento suave. Sin FFT/micrófono. Integrado en
  PantallaReproductor entre info emisora y controles.
- IndicadorReproduccion: 3 barras compactas para MiniReproductor.
  Reemplaza el icono estático, pulsa mientras hay audio activo.

 # Changelog — PluriWave
 
+## [0.5.0] — 2026-04-04
+
+### Añadido
+- **VisualizadorAudio** — visualizador de barras animadas en `PantallaReproductor`. 24 barras verticales con movimiento orgánico pseudo-aleatorio (combinación de ondas seno con fases distintas). Se activa al reproducir y decae suavemente al parar. Sin FFT real ni permisos de micrófono — animación simulada visualmente equivalente a las apps de streaming.
+- **IndicadorReproduccion** — versión compacta de 3 barras para el `MiniReproductor`. Reemplaza el icono estático de radio y pulsa mientras hay audio activo.

 ## [0.4.0] — 2026-04-04
