//! Tool-name parity ports from ophis: cobra-style command path → MCP tool
//! name, with prefix substitution and underscore joining.
//!
//! Verifies that `generate_tools` builds MCP tool names according to the
//! prefix-substitution rule: only the first space-delimited token (the root
//! command name) is replaced by the configured prefix; remaining tokens are
//! joined with underscores; hyphens inside token names are preserved.
