* fix(flannel): default the interface to each host's default IPv4 interface
- Replace the hardcoded flannel_iface: eth0 with a per-host default derived
from ansible_facts.default_ipv4.interface
- KVM/cloud hosts that are not named eth0 (e.g. enp1s0, ens3) now resolve the
interface automatically instead of failing the k3s_node_ip lookup
- Update the commented calico_iface / cilium_iface examples to match

- Fixes#621
* test(flannel): add regression test for per-host interface default
- Add a focused test that renders the sample inventory's flannel_iface
expression against fake ansible facts
- Assert a non-eth0 host (enp1s0, ens3) resolves its own interface and that
the expression defaults from ansible_facts.default_ipv4.interface
- Wire it as a local pre-commit hook (default-interface-test)
* test(molecule): assert nodes register a non-loopback InternalIP
- Add a flannel-scenario verify assertion that every node reports an
InternalIP derived from its configured flannel_iface
- Guards against k3s binding to 127.0.0.1 instead of the cluster interface
- Complements the pre-commit default-interface test with an end-to-end check
