// IdeaRowActions — Grill Me / Make Plan / Materialiseer / Archive / Open.
// Disabled-rules per M12 T-508:
//
//   Grill Me:     niet in GRILLING|PLANNING; vereist product-met-repo +
//                 connectedWorkers > 0
//   Make Plan:    alleen in GRILLED|PLAN_FAILED|PLAN_READY (re-plan); idem
//                 voorwaarden
//   Materialiseer: alleen in PLAN_READY (geen worker nodig — synchrone parser)
//   PLANNED:      alle drie disabled, "Bekijk PBI" link
//   *_FAILED:     "Probeer opnieuw" knop (= start-job opnieuw)
//
// Demo-tooltip om elke muteer-knop. connectedWorkers wordt gelezen uit
// useSoloStore (M12 grill-keuze 16 — geen lift voor v1).
