PLAN.md tells LAN hosts to start the gateway with --iface, while the binary only accepted --interface. Add --iface as a Clap alias so the documented Phase 1 command works without changing the canonical config field name. The README gateway example now uses the shorthand from the plan, and a focused parse test covers the alias mapping to the same interface field.
