Subject: [PATCH] feat(TextInput): Manejar teclas especiales internamente
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

El widget TextInput ahora procesa internamente:
- Backspace/Delete: borrar caracteres
- Flechas izq/der: mover cursor
- Home/End: inicio/fin del texto
- Shift+movimiento: selección
- Ctrl+A: seleccionar todo
- Enter: submit

Esto hace que el widget sea auto-contenido y reutilizable,
sin requerir manejo de teclas en la aplicación.
