Summary

Adds a shared service-health snapshot for aggregate dashboard tile hydration.

Why

The runtime health summary and system status aggregate both need resolved service health. Without a shared snapshot, those aggregate tile requests can duplicate every service health check.

Changes

  • Add a 30-second service health snapshot cache for aggregate tile resolution.
  • Reuse the snapshot for runtime-health-summary and system-status.
  • Key snapshots by dashboard service datasource shape plus datasource resolution context.
  • Evict failed snapshot promises so failures do not poison later aggregate refreshes.
  • Add tests for concurrent aggregate sharing and isolation across different fetch contexts.

Testing

  • bun run check
  • bun run test
  • Independent review: no blocking findings after context-aware snapshot key fix.

Notes

  • Individual service tile hydration remains unchanged.
  • packages/ui is untouched.
