nmap -sV sends plaintext probes to TLS ports (e.g. Proxmox 8006). They
stall until the host crosses --host-timeout, at which point nmap skips
the whole host and discards ports it already found — a reachable host is
returned with 0 open ports (issue #277).
Split Phase 2 into two passes: Pass A (-sS/-sT --open) discovers ports
fast with no version detection; its ports are authoritative. Pass B
(-sV --host-timeout, scoped to the found ports) enriches banners
best-effort — on timeout/failure the discovered ports are kept with
empty banners instead of losing the host.
Healthy hosts still get full-intensity -sV banners (no quality drop).
Version host-timeout is now configurable via SCANNER_VERSION_HOST_TIMEOUT
(default 60s).
