it seems that divan isn't identifying these new benchmarks |
Remove the unnecessary `mod unix` block and use `#[cfg(unix)]` attributes on imports, functions, and benchmarks. Adjust `main()` to conditionally call `divan::main()` for Unix platforms. This refactoring improves code readability and reduces module nesting without changing functionality.

… logic Replace complex child mode spawning with direct command arguments for cleaner and more maintainable benchmarks, reducing overhead and improving readability. Use "true" for quick-exit and "sleep" for enforced timeout tests.

Remove the shared bench_timeout function and directly inline its logic into timeout_quick_exit and timeout_enforced benchmarks. This simplifies the code by eliminating unnecessary abstraction for two closely related functions.
