//! I/O parameter builder method tests (TSK-072)
//!
//! ## Purpose
//!
//! Verify the six I/O parameter `with_*()` methods add the correct CLI flags.
//!
//! ## Evidence
//!
//! - `with_print(true)` adds `-p`
//! - `with_print(false)` adds nothing
//! - `with_output_format(OutputFormat::Json)` adds `--output-format json`
//! - `with_output_format(OutputFormat::StreamJson)` adds `--output-format stream-json` (hyphen!)
//! - `with_input_format(InputFormat::StreamJson)` adds `--input-format stream-json` (hyphen!)
//! - `with_include_partial_messages(true)` adds `--include-partial-messages`
//! - `with_include_partial_messages(false)` adds nothing
//! - `with_replay_user_messages(true)` adds `--replay-user-messages`
//! - `with_replay_user_messages(false)` adds nothing
//! - `with_json_schema(s)` adds `--json-schema <s>`
//!
//! ## Test Coverage Matrix
//!
//! | Method | flag present | flag absent (false) |
//! |--------|-------------|---------------------|
//! | with_print | ✅ | ✅ |
//! | with_output_format | ✅ | — |
//! | with_input_format | ✅ | — |
//! | with_include_partial_messages | ✅ | ✅ |
//! | with_replay_user_messages | ✅ | ✅ |
//! | with_json_schema | ✅ | — |
