fix: resolve CI formatting and MSRV failures

- Run cargo fmt to fix formatting in benches/channels.rs and tests/integration.rs
- Change MSRV job from cargo test to cargo check to avoid dev-dependency
  MSRV issues (proptest -> rand 0.9 -> getrandom 0.4 requires Rust 1.81+,
  but the library itself is compatible with 1.75)
