/// <summary>
/// Dapr pub/sub topic names for PIE events.
/// Consumers subscribe to these topics; PIE publishes to them via OutBox or DaprClient.
///
/// OutBox topics (guaranteed delivery — write in same DB transaction as business data):
///   pie.module.updated        → IDMS cache invalidation
///   pie.profile.published     → QuickStart / IDMS rebuild profile cache
///   pie.profile.deprecated    → mark stale in downstream
///   pie.proposal.created      → product admin notification
///   pie.proposal.reviewed     → product admin notification
///   pie.estimate.calculated   → IDMS engagement seeding
///
/// Fire-and-forget topics (non-critical analytics; loss acceptable):
///   pie.outcome.recorded      → AEO / analytics side-effect
///   pie.signal.detected       → product team notification (Phase 2)
///   pie.aeo.gap.detected      → AEO gap signals (Phase 2)
