Function spawn_daemon_with_clear_env 

pub fn spawn_daemon_with_clear_env(
    command: &mut Command,
    clear_env: bool,
) -> Result<DaemonChild>

Like spawn_daemon but with explicit control over whether the daemon’s inherited env is passed through to the child.

clear_env = false (default for spawn_daemon): child inherits the current process’s env, layered with anything set via command.env(...).

clear_env = true: child sees ONLY the explicit command.env(...) entries. Mirrors command.env_clear() semantics for callers using the manual CreateProcessW path (Rust stdlib’s env_clear flag isn’t observable through Command::get_envs, so our sanitized spawn machinery can’t otherwise honour it).
