ginuerzh 81db46b725 refactor(handler/tunnel): code review fixes and entrypoint subpackage extraction
- Fix dead-code branch in bind.go host assignment (always use endpoint hash)
- Return descriptive error on bypass match in connect.go (was masking as success)
- Update bypass test in connect_test.go for new error behavior
- Extract entrypoint subpackage from monolithic entrypoint.go (6 files)
- Fix observeStats event-loss bug (break -> fallthrough on retry success)
- Add 47 unit tests across handler, connect, bind, metadata packages
- Add architecture doc comments to all key files
- Build and vet clean, 173 tests pass with -race

ginuerzh 31878a72ec docs(handler/tunnel): add architecture documentation and fix observeStats event loss
- Add package-level architecture doc in handler.go covering:
  - NAT traversal reverse proxy architecture
  - CmdBind/CmdConnect roles and data flow
  - Connector lifecycle and waitClose semantics
  - Entrypoint protocol dispatch (first-byte sniffing)
  - SD fallback behavior
- Add data-flow-oriented doc comments to all business files:
  - entrypoint.go: protocol dispatch, dial flow
  - connector.go: Connector/ConnectorPool semantics
  - dialer.go: two-phase dial strategy
  - tunnel.go: MaxWeight semantics, selection algorithm
  - bind.go: 6-step CmdBind flow
  - connect.go: CmdConnect flow with relay framing
  - ephttp.go, eptls.go, eprelay.go: per-protocol entrypoint flow
- Fix observeStats: after successful error retry, also flush new events
  instead of skipping the current tick (handler.go:261-271)
- Add test for observeStats retry-then-flush (handler_test.go)

ginuerzh 382d47ea12 fix: nil HTTP recorder ref in WebSocket goroutines, add tunnel loop detection
- handler/http/websocket, forwarder/sniffer_ws, sniffing/sniffer_ws: nil
  ro2.HTTP in WebSocket copy goroutines to avoid data races on the shared
  HTTP recorder object
- handler/tunnel/bind: remove ingress rule check that incorrectly
  overrode the endpoint host for non-matching ingress rules
- handler/tunnel/entrypoint: add forwarding loop detection by checking
  Gost-Forwarded-Node header for the entrypoint's own node ID

ginuerzh b8d9c79f72 fix: handle empty host in relay AddrFeature ParseFrom for bind addresses
When rtcp listener calls Router.Bind with ":8000" (port-only address),
the relay AddrFeature.ParseFrom fails because net.SplitHostPort returns
an empty host. This leaves AType at default 0, causing AddrFeature.Encode
to return ErrBadAddrType.

Fix by normalizing port-only addresses to "0.0.0.0:<port>" in both tunnel
and relay connectors before ParseFrom. Also fix error check on
resp.WriteTo in the tunnel handler's handleBind to prevent silent
protocol desync.
