Summary

Implements two issues assigned to @NikeRegy:

Issue #13: Micro-Meter Provisioning Flow with QR Generators

  • QR code generation: Uses qrcode library to render actual QR canvas (not placeholder text)
  • API submission: Calls api.post('/api/provision', ...) for on-chain provisioning
  • Loading/error states: Spinner animation during submission, error messages with retry support
  • Keyboard navigation: Enter to advance, Escape to go back through all wizard steps
  • QR error recovery: Retry button regenerates QR when generation fails

Issue #10: Web Worker Multi-Threaded Chunk Aggregators

  • useWorker hook: Full lifecycle wrapper (instantiate, postMessage, receive, terminate)
  • Main-thread fallback: Graceful degradation when worker creation fails
  • Typed interfaces: WorkerPayload, AggregationChunk, TransformedValue with type-safe result handling
  • Unmount safety: mountedRef pattern prevents state updates after cleanup

CI Checks

  • ✅ TypeScript tsc --noEmit passes
  • ✅ 32/32 unit tests passing
  • ✅ ESLint clean (zero warnings/errors)
  • npm run build succeeds

Closes #13, closes #10

- Issue Utility-Protocol#13: Rewrite Provisioner with real qrcode-to-canvas generation,
  API submission via api.post, loading/error states per step,
  keyboard navigation (Enter/Escape), and spinner animations
- Issue Utility-Protocol#10: Create useWorker hook wrapping data.worker.ts lifecycle
  (instantiate, postMessage, receive, terminate) with typed payloads
  and main-thread fallback on worker failure

Closes Utility-Protocol#13, closes Utility-Protocol#10
