ginuerzh 3b3eaa609a fix(listener/pht): set X-Accel-Buffering to fix hang behind Nginx (issue #721)
The /pull handler streams data as base64 chunks with a flush per chunk.
With Nginx proxy_buffering on (the default), these tiny chunks and the
heartbeat newlines are buffered and never flushed to the client, so
active data transfer hangs until the buffer fills or the upstream closes.

Set X-Accel-Buffering: no on the pull response so Nginx forwards each
flushed chunk immediately without buffering. Nginx consumes the header
(it is not forwarded to the client) and it is inert when no proxy sits
in front of the listener, so it is safe to set unconditionally.

Covers pht, phts and h3, which share the same Server handler.

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.
