feat(plugins): actualiza completions, agrega markview/img-clip/mini.diff, mejora codecompanion

- Se actualizó el lockfile de plugins a las últimas versiones y se añadieron nuevos plugins.
- Se agregó `markview.nvim` para una mejor previsualización de markdown/codecompanion, reemplazando `render-markdown.nvim` por mayor compatibilidad y funcionalidades.
- Se incorporó `img-clip.nvim` para pegar imágenes fácilmente en buffers de codecompanion, con plantilla personalizada y soporte de rutas absolutas.
- Se añadió `mini.diff.nvim` para visualización ligera de diferencias, integrado como proveedor de diff en codecompanion.
- Mejoras en la configuración de codecompanion:
  - Añadido selector de modelo preferido para adaptadores LLM, priorizando modelos Qwen2.5-coder.
  - Se cambió el adaptador por defecto de chat/inline a Copilot para mejores resultados.
  - Integración de la extensión `mcphub.nvim` para funcionalidades adicionales en codecompanion.
  - Mejor mapeo de iconos para autocompletado.
- Limpieza en la configuración de fuentes de autocompletado para mayor consistencia.
- Se eliminó la configuración del plugin `render-markdown.nvim` (obsoleto).

Estos cambios mejoran el renderizado de markdown, manejo de imágenes, visualización de diferencias y el flujo de trabajo con LLM en Neovim.
