claude_runner_core 1.0.0

//! Environment variable setting tests
//!
//! ## Purpose
//!
//! Verify `build_command()` sets correct environment variables for all parameters.
//!
//! ## Evidence
//!
//! - Each parameter sets its corresponding environment variable
//! - Environment variable names match Claude Code expectations
//! - Values are correctly formatted (strings, booleans, numbers)
