lesavka/testing/tests/client_main_binary_contract.rs

//! Integration coverage for client binary startup wiring.
//!
//! Scope: include `client/src/main.rs` and exercise startup guards/tracing
//! branches without launching the full runtime app loop.
//! Targets: `client/src/main.rs`.
//! Why: keep client startup behavior deterministic and directly attributed to
//! the binary entrypoint source file.
