IPv6 hosts are not supported in browser_open

Error message

IPv6 hosts are not supported in browser_open

What it means

extract_host rejects bracketed IPv6 authority literals. The allowlist matcher compares lowercase hostnames, and IPv6 literals are not supported by that matching or by the private-host classification used here, so they are refused explicitly.
