ginuerzh 7b088f8f42 feat(socks5): add Tor RESOLVE/RESOLVE_PTR extension command support (gost#524)
Adds SOCKS5 handler and connector support for Tor-specific RESOLVE (0xF0)
and RESOLVE_PTR (0xF1) commands, enabling tools like torsocks and
tor-resolve to work through GOST when forwarding to a Tor SOCKS5 proxy.

- Define CmdResolve (0xF0) and CmdResolvePTR (0xF1) in x/internal/util/socks
- Add ContextWithSocks5Cmd/Socks5CmdFromContext for per-request command override
- Connector reads context command, sends it upstream, returns resolveConn
- resolveConn wraps net.Conn and exposes resolved addr via Metadata()
- Handler dispatches 0xF0/0xF1 to handleResolve/handleResolvePTR
- Gate behind enableTor metadata (tor=true), reject with CmdUnsupported by default
- 9 unit tests across ctx/, connector/, handler/ packages

x

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.

See CLAUDE.md for detailed architecture and conventions.
