v0.1.0

The first tagged release: the ZAPI-interop core, all four SAVNET slices, three native protocol daemons (bgpd with RPKI/ASPA/OTC from the start, ospfd v2+v3 AF-generic, bfdd with receive-side TTL enforcement) — all live-proven against real FRR 10.2.2 — plus the management plane foundation (configd, vtyd, rousterctl). Gate: 1468 tests green; 34-script container smoke suite; Linux CI on every push. MIT.
