ginuerzh 8787aff108 tun: a handler that owns a p2p hub and bridges streams into it
p2p.go was a complete engine with nothing driving it: no handler.Handler,
so no GOST service could reach the hub and a spoke's registration frame had
no path to one at all.

NewP2PHandler takes the tun device conn and an auther, builds the peerTable
(no TTL — a stream close says a peer is gone outright, where a socket peer
has only silence to guess from), the peerRouter and the p2pHub, and starts
the device reader. Handle installs one accepted stream under its remote
address — the peer key the p2p host stamped on it, replacing whatever a
reconnect left behind — and feeds its datagrams to the hub until the read
fails. Teardown is peerGone and nothing else: it reclaims a peer's routes
only while that stream still holds its key, so a stale stream ending cannot
cut off the live connection its peer already replaced it with.

ownNets comes off the device conn's context, the two steps server.go's Handle
already uses, because a nil answer silently disables the self-route guard.

Handle returns the read error unwrapped. io.EOF, net.ErrClosed and
context.Canceled are what isServerError calls an ordinary end, so a peer
reconnecting would otherwise land in someone's error log.

The p2p half of the compat suite now runs against the real handler and the
real hub rather than reporting itself unavailable: the same six assertions,
the same two cases skipped without an auther. A second p2p case covers the
reconnect, which is the only way the suite would notice a peerGone that
dropped routes unconditionally — a hub that did so passes every shared case.

The implementation layer for the GOST proxy framework. Every interface defined in core/ is implemented here — handlers, listeners, dialers, connectors, plus config parsing, registries, and all cross-cutting concerns.

Package layout

Directory Purpose
handler/ Protocol handlers (http, socks4/5, ss, ssh, tunnel, tun, dns, redirect, etc.)
listener/ Protocol listeners (tcp, tls, ws, http2/3, quic, kcp, icmp, tun, udp, etc.)
dialer/ Outbound dialers (tcp, tls, ws, http2/3, quic, grpc, ssh, wg, kcp, icmp, etc.)
connector/ Destination connectors (http, socks4/5, ss, ssh, relay, tunnel, direct, etc.)
config/ Config struct, YAML/JSON parsing, and service construction
registry/ Typed global registries for all component types
service/ Accept loop wiring listener + handler
chain/ Multi-hop forwarding chain and route implementation
router/ Route table router (destination-based routing)
hop/ Node group with load-balanced selection
selector/ Load-balancing strategies (round-robin, random, weighted, hash)
auth/, bypass/, admission/ Authentication, bypass rules, admission control
resolver/, hosts/ DNS resolution and host mapping
limiter/ Traffic, connection, and rate limiters
recorder/, observer/ Traffic recording and observability
ingress/, sd/, routing/ Ingress control, service discovery, routing rules
logger/, metrics/, api/ Logging, Prometheus metrics, Web API
metadata/, ctx/ Metadata key-value system and context propagation
internal/ Shared internals — not importable externally

Component pattern

Every handler, listener, dialer, and connector follows the same pattern: init() registers a constructor into a global registry, the constructor takes functional options, and Init(metadata.Metadata) extracts typed configuration from the metadata key-value map.
