- Fix bidirectional stream handling: responder uses accept_bi() instead
of open_bi() so both sides communicate on the same stream
- Add live_receive_loop to accept incoming bi-streams during ongoing
sync (peer's push loop opens new streams per batch)
- Split live_sync_loop into live_push_loop + live_receive_loop running
concurrently via tokio::select in new run_live_sync()
- Update handle_incoming to run live sync after initial reconciliation
- Add direct peer connection via ticket files (EndpointAddr JSON
exchange) for local testing without gossip bootstrap
- Add CAN_PORT env var override for running multiple CAN instances
- Add integration test binary (sync_test.rs): starts 2 CAN services +
2 sync agents, ingests files on each side, verifies bidirectional
sync with 4 test cases (A→B, B→A, batch, count match)
- Add PowerShell script (run-integration-test.ps1) for one-command test
