V0-integrering: polert hull-diagram

Integrerer V0-eksporten for hole-diagram-view.tsx. Traff props-
kontrakten i prompten eksakt -- ingen integreringsjustering nødvendig,
tsc rent på første forsøk. Egne tillegg fra V0 utover prompten: full
aria-label-oppsummering av hele diagrammet for skjermlesere, lett
kollisjons-unngåelse for nære hindringsetiketter.

Re-verifisert i scratch mot samme kjente syntetiske geometri som den
midlertidige hånd-kodede versjonen -- identiske tall/posisjoner.
Lys+mørk bekreftet.
