The cache-hit path (serveCachedResponse) recorded on the same HandlerRecorderObject
as the calling handler's deferred Record(), producing two records per request.
Copy ro at HandleHTTP entry so the sniffer's internal recording stays isolated
from the caller's defer. Also zero ro.Time when the sniffer takes over, so the
handler's defer Record() skips the now-redundant connection-level record.
Fixes 10 files across sniffer and all 8 handlers that support sniffed HTTP forwarding.
Populate the existing Node field on HandlerRecorderObject after every
hop.Select() call in forwarder code paths. Previously the field was
never set, though it was already consumed by tunnel entrypoint HTTP
handler (ephttp.go:145) and tested for round-trip in recorder tests.
When sniffing is enabled, the sniffer extracts the real domain from HTTP
Host header or TLS SNI and checks bypass rules against it. However, most
handlers were not passing WithBypass(...) to the sniffer, so the sniffer
internal bypass check was always skipped.
Additionally, the TLS-to-HTTP fallback paths in internal util sniffer
and forwarder also omitted bypass when constructing options for the
recursive HandleHTTP call after decrypting TLS.
Add WithBypass to all sniffer call sites that were missing it across
handlers (http, relay, socks4, socks5, ss, sshd, unix) and internal
TLS fallback paths.
Also fix import ordering in handler/http/connect.go.

The readTimeout field (default 15s) was being applied via xnet.Pipe to both
directions of a bidirectional proxy connection. During asymmetric transfers
(e.g. HTTP file download), the direction reading from the tunnel sees no
data after the initial request is forwarded, causing SetReadDeadline to fire
after 15s and abort the entire transfer.
Fix: add a separate idleTimeout field (default 0=disabled) to the metadata
structs in both forward/local and forward/remote handlers, and switch
xnet.Pipe to use idleTimeout instead of readTimeout. The readTimeout field
now only applies to the initial protocol sniffing/handshake phase.
Also document readTimeout vs idleTimeout semantics across all 24 locations
in the x/ module where these timeouts appear:
- readTimeout: handshake sniffing deadline (handlers), upstream response
header timeout (http.Transport), or transport-level read deadline
- idleTimeout: idle read deadline per Pipe direction (0=disabled)
- ReadTimeout on Sniffer/SnifferBuilder: upstream response header/TLS
handshake read timeout during sniffing
