DC-153: provider.syncAccess enforcement wiring (tailscale ACL push + wireguard nftables apply) + contract tests

+ * DC-153 syncAccess contract suite — exercises the src/network/acl-sync.js
+ * adapter (the injectable Tailscale enforcement engine) directly, plus the
+ * cross-provider guarantees the judge gate asked for: shapes pass through,
+ * error classes map to ProviderError codes, success shapes hold, and the
+ * DEFAULT construction paths run the real DC-148/DC-151 engines against
+ * injected coord/exec mocks.
+ *
+ * Provider-level behavior tests live in network-provider-{tailscale,wireguard}.test.js.
