Adding CLI Arguments

Client CLI arguments are defined in a shared struct to avoid duplication:

  1. Add to ClientArgs in modelexpress_common/src/client_config.rs

    • Single source of truth for shared arguments
    • Register the variable name in modelexpress_common/src/envs.rs and reference the constant: #[arg(long, env = crate::envs::MODEL_EXPRESS_...)] (never a bare string literal, so the CLI and the envs getters cannot drift). All env-var names live in modelexpress_common/src/envs.rs (Rust) and modelexpress/envs.py (Python).
    • Do NOT use -v short flag (reserved for CLI's verbose)

  2. Update ClientConfig::load() in the same file

    • Add override logic in the "APPLY CLI ARGUMENT OVERRIDES" section

  3. Do NOT duplicate in Cli (modelexpress_client/src/bin/modules/args.rs)

    • Cli embeds ClientArgs via #[command(flatten)]
    • Only add CLI-specific arguments there (e.g., --format, --verbose)

  4. Add tests in the tests module of client_config.rs
