feat: Add HTTP server/client E2E test for net plugin

- Implement full HTTP flow test: server → client → accept → respond → readBody
- All HTTP Box types working correctly (HttpServerBox, HttpClientBox, HttpRequestBox, HttpResponseBox)
- Handle type encoding for plugin method arguments working properly
- Test validates complete HTTP request/response cycle
- Net plugin E2E test passing ✅

HTTPネットワークプラグインのE2Eテスト追加
- サーバー起動からレスポンス読み取りまでの完全なフロー検証
- Handle型引数のTLVエンコーディングも正常動作
- 非同期HTTPフローの完全動作確認
