1. targets.toml: [perfil.escritorio-gnome] (9 raíces de sesión, cola incoming-gnome)
   ⇒ `yupana objetivo` ya lo ve; fluye por targets.py. build-state lo SALTA hasta
   que la cola se cargue (--gnome), así declararlo no reporta raíces fantasma.
2. seed-gnome.py OPTIMIZADO: hornea la triage (sustitución/tooling/opcional/espinazo)
   como HIPÓTESIS con el caveat "el cierre de nixpkgs sobreestima ~5-10×", marca el
   keystone (spidermonkey→gjs→gnome-shell), y deja de mentir con el 465 crudo. El
   espinazo (353) se reporta como COTA ALTA, no como lista de build.

Falta (se activa al autorar): grafo build-state-gnome + flag --gnome ⇒ keystones/
drenar nativos sobre GNOME. Hoy la capa OBJETIVO del yupana-gnome está; la GRAFO no.
