namefi-dyndns

Use when a user wants something they are developing reachable on a real hostname without a static IP — show off a local app on their domain, reach a home server or NAS or VPS from outside, an IP that keeps changing, set up dynamic DNS, point a Namefi domain at this machine, or check whether an ISP is CGNAT — and it is not yet clear whether they are on a VPS or behind home NAT, or which tool (namefi CLI, ddclient, none) they should use. This is the front door that diagnoses the situation and hands off to the right sub-skill. Takes an optional mode argument — simple (default; pick defaults from detection and present one plan to accept or modify) or advanced (confirm each decision individually).
