Local-only developer utility that authenticates against the running backend,
captures the current /api/network snapshot, and writes it to
src/lib/person/genealogy/__fixtures__/stammbaum.json. Sanity gates exit
non-zero on a vacuous capture (< 50 nodes, < 5 generations, 0 SPOUSE_OF
edges). Fixture and script land together so the fixture is reproducible from
the script that generated it.
Captured snapshot: 62 nodes, 43 edges, 28 SPOUSE_OF (0 with fromYear),
generations G0-G4. Albert de Gruyter is the canonical multi-spouse case with
4 marriages.
