//! Purpose: Build argv-only managed subprocess commands.
//!
//! Responsibilities:
//! - Validate argv inputs before constructing `std::process::Command` values.
//! - Reject empty command vectors or blank program entries.
//!
//! Scope:
//! - Argv validation and command construction only.
//!
//! Usage:
//! - Used by managed subprocess entrypoints that accept `SafeCommand` inputs.
//!
//! Invariants/Assumptions:
//! - Managed subprocess execution stays argv-first with no implicit shell parsing.
//! - The first argv element is always the executable path/program name.
