Agregar respaldo y restauracion de Firefox y VSCodium nativo

Firefox: captura del perfil snap (marcadores, contrasenas, extensiones,
cookies, contenedores, prefs; excluye caches y storage de sitios) y modulo
de restauracion idempotente.

VSCodium: pasa a instalacion nativa via repo apt oficial (clave GPG +
sources) en lugar de flatpak; captura settings, snippets, perfiles, estado
de workspaces y lista de extensiones (excluye cache de redhat.java).
