//! Command Dispatch Tests for RAPS CLI
//!
//! These tests verify that all CLI commands are properly dispatched without panicking.
//! They catch routing bugs like incorrect std::mem::replace patterns that corrupt command state.
//!
//! Run with: `cargo test --test command_dispatch_test`
//! Or run all tests: `cargo test`
