pnpm dev:spinner,pnpm dev:chat,pnpm dev:upgrade) - these were only briefly tested and the upgrade demo wasn't tested at alldispatchmethod in engine.ts (line 218) - it's a stub for future async event dispatchRecommended test plan:
pnpm buildin the inquirerer packageNotes
Spinnerclass accepts aUIEnginein constructor but doesn't use it (may be for future extensibility)Link to Devin run: https://app.devin.ai/sessions/e424b0eaba2f4789815bb0cc22ca6233
