Base del merge a tres bandas: git 0.9.5 de epsylon, esta rama y el src de la
APK oficial 1.3.1 (la variante movil: OASIS_MOBILE, regex sin \p{}, audio y
video de Android). Corre en el mismo nodejs-mobile 18.20.4 que ya usabamos.
Se conserva de la rama: Karvan, identidades y multicuenta, topbar y barra
inferior, borrado de EXIF sin sharp, filtro hot del foro, RTC sin STUN y los
modulos apagados en movil (wallet, banking, torrents).
Se toma de upstream lo que ya hace de serie: respuesta citada en chats, ssb-lan
en movil, configuracion en ~/.ssb/oasis (sobrevive a reinstalar el backend).
El asistente de bienvenida deja elegir workflow tambien en movil.
