feat(ui): reemplaza solarized-osaka y lualine.nvim por esquema de color y barra de estado nativos

- Se eliminaron los plugins externos para el esquema de color (solarized-osaka) y la barra de estado (lualine.nvim).
- Se agregó una implementación nativa inspirada en Solarized Osaka en `config.native-colorscheme`.
- Se agregó una barra de estado nativa en `config.native-statusline` para mejorar el rendimiento y la personalización.
- Se actualizó la configuración para cargar la interfaz nativa y establecer opciones relacionadas desde el inicio.
- Motivación: Reducir dependencias de plugins, mejorar el tiempo de inicio y permitir una personalización más profunda de los elementos de la interfaz.
