A small bubbletea TUI that reads maglev.yaml (repeatable --config), enumerates every VIP, and probes each from outside the load balancer on a tight cadence (default 100ms, ±10% jitter). HTTP/HTTPS VIPs get a GET against a configurable URI (default /.well-known/ipng/healthz) with per-VIP rolling latency (p50/p95/p99/max), lifetime N/FAIL counters, LAST status, and a response-header tally. Non-HTTP VIPs get a TCP connect probe. A bounded error panel classifies anomalies as timeout / http-err / net-err / spike and auto-sizes to fill the screen. Utility: during a failover drill (backend flap, AS drain, config push) the tally panel shows which backend each VIP is actually steering to, with two-colour activity highlighting over a 5s window — white = receiving traffic, grey = drained. Paired with the rolling OK%/latency columns it gives an at-a-glance answer to "is the VIP healthy from the outside right now, and which backend is it hitting", without relying on maglevd's own view of the world. Also bumps Makefile/go.mod to build the new binary.
