// cost-outcome — thin wrapper around `hooks model-outcome` so cost-optimize
// recommendations can be emitted as pre-formatted shell commands. The agent
// (or human) runs this once per applied recommendation and the router learns.
//
// Usage:
//   node scripts/outcome.mjs <task-description> <model> <outcome>
//     outcome ∈ { success, escalated, failure }
//
// Example:
//   node scripts/outcome.mjs "format imports" haiku success
//   node scripts/outcome.mjs "design auth flow" sonnet escalated
//
// Why a wrapper: `hooks model-outcome` takes `-t -m -o` and quoting through
// shell pipelines is error-prone. This script uses spawnSync with explicit
// argv so a task description with quotes/newlines is preserved.
