src/cli/transport.rs

Used multi_thread tokio runtime for tests to handle blocking send_tcp + async mock server

Mock server uses stream.into_split() for independent read/write halves

Fixed unused `mut` warning on reader variable

T01: Added 3 integration tests (round-trip, connection refused, liveness check) exercising send_tcp() and is_alive_tcp() against a mock TCP server

Added 3 integration tests (round-trip, connection refused, liveness check) exercising send_tcp() and is_alive_tcp() against a mock TCP server

What Happened

Added a #[cfg(test)] mod integration_tests module to src/cli/transport.rs with three integration tests:

test_send_tcp_round_trip: Spawns an async mock TCP server (tokio::net::TcpListener on 127.0.0.1:0) that reads one JSON-line request and responds with a valid Response. Calls send_tcp(Request::Sessions{limit:20}, addr) and asserts resp.ok == true.
test_send_tcp_connection_refused: Calls send_tcp against port 59876 with no listener. Asserts Err is returned.
test_is_alive_tcp_false: Calls is_alive_tcp against port 59877 (unused). Asserts false.

Key design decisions:

Used #[tokio::test(flavor = "multi_thread")] for all tests because send_tcp uses blocking std::net::TcpStream while the mock server uses async tokio::net::TcpListener — they must run on different threads.
Mock server reads one line via tokio::io::BufReader, then writes the response via stream.into_split() to get independent read/write halves.
Tests use crate::ipc::{Request, Response} for proper type integration.
All tests are self-contained with no external dependencies beyond existing tokio and serde_json.

Verification

cargo test integration_tests -- --test-threads=1: all 3 tests passed (test_send_tcp_round_trip, test_send_tcp_connection_refused, test_is_alive_tcp_false). cargo check --target x86_64-pc-windows-msvc: passed. Linux cross-compile skipped (no x86_64-linux-gnu-gcc on this Windows machine — environment limitation, not a code issue).
