ginuerzh 3246b39c93 refactor(handler/http): split handler monolith into 7 focused files with 96 unit tests
Extract the 1024-line handler.go into concern-focused files:
  util.go       — 5 pure functions (decodeServerName, basicProxyAuth, upgradeType,
                  normalizeHostPort, buildConnectResponse) — 100% coverage
  auth.go       — authenticate (5 probe-resistance strategies + knock) + checkRateLimit
  connect.go    — handleConnect, sniffAndHandle, dial, setupTrafficLimiter
  proxy.go      — handleProxy keep-alive loop, proxyRoundTrip, handleUpgradeResponse
  websocket.go  — WebSocket frame sniffing/recording with rate-limited sampling
  udp.go        — UDP-over-HTTP relay with SOCKS5 tunnel
  metadata.go   — metadata struct, parseMetadata, probeResistance type

Key improvements:
- Transport injection (http.RoundTripper field) enables testing without real network
- Nil Router guards in dial, handleUDP, and nil Addr guard in checkRateLimit
- Pure functions converted from methods to package-level (no state dependency)
- setupTrafficLimiter returns cleanup closure to preserve defer lifetime
- handleConnect accepts caller's resp for correct recorder status capture
- Comprehensive package doc with full request-flow documentation

96 tests: 100% on pure functions, 86% on metadata parsing, 55% overall (integration
paths verified by e2e tests).

Andrew Beresford 290e9c37d5 Make pipe read timeout configurable via idleTimeout metadata
The 30s hardcoded readTimeout in Pipe() caused all CONNECT tunnel
connections to be hard-closed after 30s of inactivity, breaking
WebSocket and long-polling connections through the proxy.

Pipe() now accepts a WithReadTimeout(d) option. When d is 0 (the
default) no read deadline is set, relying on TCP keepalives or context
cancellation to detect dead connections instead.

The HTTP handler exposes this as the idleTimeout metadata key.
