Add configurable TCP keepalive (keepalive, keepalive.idle, keepalive.interval, keepalive.count) to all TCP-based transport types: tls, mtls, mtcp, ws/wss, mws/mwss, http2, ssh, sshd listeners and tls, mtls, mtcp, ws/wss, mws/mwss, ssh, sshd dialers. For types that already use "keepalive" for an app-level protocol (grpc listener/dialer, ws/mws dialers, ssh/sshd dialers), the TCP keepalive parameters are exposed under the tcp.keepalive.* prefix to avoid ambiguity. Also extract shared helpers into internal/net/keepalive.go: - WrapKeepaliveListener: applies KeepAliveConfig on every accepted TCPConn - ApplyKeepalive: applies KeepAliveConfig to a single TCPConn Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
