Línea de trabajo

Comienza con MODULE.bazel y app.py en la reproducción mínima enlazada y luego ejecuta `bazel run //app:app` con rules_python 0.31.0 y `--noenable_bzlmod` para comparar. Rastrea el lanzamiento de `py_binary` bajo bazel_dep y confirma que el arreglo evita el aborto de Tkinter XCB, preservando al mismo tiempo el inicio normal de la aplicación.
