// Test-helper voor M8 acceptatie. Muteert een task of story rechtstreeks
// in de DB om realtime-events te triggeren — alsof MCP of een andere
// schrijver het zou doen. Niet voor productiegebruik.
//
// Gebruik:
//   tsx scripts/realtime-mutate.ts move <taskId> <status>
//   tsx scripts/realtime-mutate.ts touch task <taskId>
//   tsx scripts/realtime-mutate.ts touch story <storyId>
//   tsx scripts/realtime-mutate.ts rename story <storyId> <new title>
//   tsx scripts/realtime-mutate.ts list-tasks    # toont id + status van assigned tasks
