// Package runtimecmd parses and builds the CLI command lines used to invoke a
// coding-agent runtime (e.g. `codex exec <prompt>`, `claude -p <prompt>`). It was
// extracted from the former rpi engine (age-tlj6 teardown): the helpers are a
// reusable utility with no orchestration-engine coupling, consumed by the eval
// runtime. Pure string functions — no I/O, no side effects.
