ci: retrigger workflow

**Fix 1 — HTTP cleartext (streams sin HTTPS):**
- Añadir android/app/src/main/res/xml/network_security_config.xml con
  cleartextTrafficPermitted=true para permitir streams de radio HTTP
- Referenciar en AndroidManifest.xml con android:networkSecurityConfig
- Resuelve: 'Cleartext HTTP traffic to [host] not permitted' en ExoPlayer
- Radio Paradise (Dance Wave, HTTP) y otras radios HTTP funcionan ahora

**Fix 2 — Gestión de error TYPE_SOURCE y todos los PlaybackException:**
- Añadir listener en playbackEventStream.onError en PluriWaveAudioHandler
- _gestionarErrorReproduccion() emite AudioProcessingState.error al UI,
  loggea el error y resetea el player a estado idle limpio
- _mensajeAmigable() traduce códigos ERROR_CODE_IO_*, ERROR_CODE_PARSING_*,
  ERROR_CODE_DECODING_* y mensajes de Cleartext/HandshakeException a texto legible
- EstadoRadio.reproducir() captura la excepción y cancela el timer si estaba activo
- EstadoRadio escucha el estadoStream y cancela timer ante cualquier error

**Fix 3 — Artwork con certificado autofirmado:**
- errorWidget en CachedNetworkImage captura HandshakeException silenciosamente
- Muestra _iconoFallback (icono de radio) en lugar de imagen rota
- El error de artwork no se propaga ni interrumpe la reproducción

**Fix 4 — UI consistente en estado de error:**
- PantallaReproductor._Controles muestra mensaje + botón Reintentar en error
- PantallaReproductor._Artwork muestra overlay wifi_off en estado de error
- MiniReproductor muestra botón refresh (reintentar) en estado de error
- EstadoReproduccion.error ya estaba definido; ahora el estadoStream lo emite
- Timer cancelado automáticamente cuando la reproducción falla
- Test de smoke corregido (boilerplate MyApp → placeholder válido)

Fixes: cleartext HTTP, cert autofirmado, ExoPlayer TYPE_SOURCE, UI inconsistente

 # Changelog — PluriWave
 
+## [0.4.0] — 2026-04-04
+
+### Añadido
+- **PantallaReproductor** — pantalla completa del reproductor. Accesible tocando MiniReproductor o cualquier emisora. Incluye: artwork/logo grande con sombra animada al reproducir, nombre + chips info (país, idioma), codec/bitrate, controles play/pause/stop con indicador "en vivo", botón favorito (toggle), widget de timer (iniciar/cancelar desde la pantalla), animación de entrada slide-up. Transición pageRoute desde cualquier pantalla.
+- **PantallaAjustes** — pantalla de ajustes básica (tab nuevo en NavigationBar). Muestra estado del sistema (filtro emisoras, audio background), conteo de favoritos, preview de features próximas (Export/Import, radio personalizada, ecualizador).
+- **MiniReproductor** — ahora es tappable: toca la barra para abrir PantallaReproductor.
+- **NavigationBar** — añadido tab "Ajustes" (4 destinos: Inicio/Buscar/Favoritos/Ajustes).
+
+## [0.3.0] — 2026-04-04
+
+### Fixes (prioridad alta — petición WhikY)
+
+- **Audio en background** — `ServicioAudio` refactorizado para delegar toda la reproducción a `PluriWaveAudioHandler` (audio_service). La notificación foreground de Android mantiene el audio vivo al apagar pantalla. Handler inicializado en `main.dart` con `AudioService.init()` y registrado globalmente. `onTaskRemoved` libera recursos al cerrar la app. `mediaItem` propagado con nombre, artista y artwork de la emisora.
+- **Filtrar emisoras rotas** — `ServicioRadio` añade `lastcheckok=1` en todas las peticiones a la API. Solo se devuelven emisoras verificadas como funcionales por Radio Browser.
+- **Errores como SnackBar** — `EstadoRadio` emite errores de reproducción y búsqueda por `errorStream` (StreamController broadcast). `_PaginaPrincipalState.didChangeDependencies` suscribe al stream y muestra `SnackBar` flotante de 3 segundos. Los errores de carga de lista siguen como banner inline (no bloquean la UI).
+- **Icono de app** — Generado con Stable Diffusion XL: diseño morado, ondas de radio blancas, estilo Material You. Todos los tamaños Android generados (mdpi/hdpi/xhdpi/xxhdpi/xxxhdpi, 48-192px). `ic_launcher_round` añadido. `android:roundIcon` en AndroidManifest.
+
+### Ficheros modificados
+| Fichero | Cambio |
+|---|---|
+| `lib/main.dart` | `AudioService.init()` + `registrarHandler()` |
+| `lib/servicios/servicio_audio.dart` | Arquitectura background completa |
+| `lib/servicios/servicio_radio.dart` | `lastcheckok=1` en todas las peticiones |
+| `lib/estado/estado_radio.dart` | `errorStream` en lugar de campo `_error` |
+| `lib/app.dart` | Listener `errorStream` → SnackBar + theme SnackBar |
+| `android/app/src/main/AndroidManifest.xml` | `roundIcon` |
+| `android/app/src/main/res/mipmap-*/` | Iconos generados (5 densidades) |
