// gsd-cursor-subagent-stop.js — Cursor subagentStop hook (ADR-1239 / #2089)
//
// Cursor invokes this script when a subagent session completes.
// Protocol: JSON from Cursor on stdin; JSON response on stdout.
//
// Input schema (cursor subagentStop):
//   { session_id, conversation_id, generation_id, model, hook_event_name,
//     cursor_version, workspace_roots, user_email, transcript_path }
//
// Output schema (cursor subagentStop):
//   { additional_context?: string }
//
// Behaviour:
//   - Reminds the orchestrating agent to check the subagent's output.
//   - Fails open: any error silently exits 0.
//
// Cursor docs: https://cursor.com/docs/hooks
