sniffer_http:
When DNS override directs multiple domains to the same proxy IP, the
browser may reuse a keep-alive connection for a different host. The
HTTP keep-alive loop now detects Host header changes and re-dials a
new upstream connection with correct node selection, preventing CDN
errors (Fastly unknown domain, CloudFront 403).
sniffer_tls:
Return a descriptive error when TLS ClientHello has no SNI, instead
of silently returning nil. This makes the connection drop visible in
logs and recorder output.
