ralph-agent-loop 0.4.0

//! Purpose: request parsing coverage for task command input normalization.
//!
//! Responsibilities:
//! - Validate positional-argument joining and whitespace trimming behavior.
//! - Verify error handling for missing or whitespace-only requests.
//! - Preserve special characters, multilingual text, newlines, tabs, and internal whitespace.
//!
//! Scope:
//! - `task_cmd::read_request_from_args_or_reader` behavior only.
//!
//! Usage:
//! - Uses `super::*;` to access the shared suite imports.
//!
//! Invariants/assumptions callers must respect:
//! - These tests intentionally use a `Cursor` reader instead of real stdin to avoid hangs in non-terminal CI environments.
