// Alpha end-to-end verification test.
//
// Runs the actual FRB-loaded Rust bridge against cn.teamspeak.app.
// This is the empirical evidence that the Alpha build's
// connect → snapshot → disconnect cycle works through the full
//   Dart UI thread → flutter_rust_bridge → chanora_bridge cdylib →
//   chanora_core → chanora_protocol → tsclientlib → network
// path.
//
// Tagged with the network-required marker so future CI can opt out.
//
// Requirement trace (SWE.5 / SWE.6 — end-to-end connect path):
//   SRS-001..SRS-030 (server connection flow), SRS-031..SRS-060 (channel/client snapshot),
//   SAD-032, SAD-033, SAD-040, SAD-041 (protocol adapter + bridge facade),
//   SDD-046, SDD-047 (typed DTOs + event mapping).
//   Verification-plan rows: SWE5-IV-008, SWE5-IV-009 (swe5-software-integration-verification-plan.md);
//   SWE6-SV-001, SWE6-SV-002 (swe6-software-verification-plan.md).
// For now it's just a regular flutter_test test.
