Set up Cursor Cloud dev environment (AGENTS.md)

[Cookie774-GameDev]

Summary

Sets up and verifies the development environment for the VibeSpace desktop app, and documents durable cloud-agent guidance in AGENTS.md.

• Update script – npm install (root npm workspace installs the app workspace).
• AGENTS.md – adds a ## Cursor Cloud specific instructions section covering how to run the app (npm run jarvis → Vite on :5173), offline mock-LLM behavior, the expected "backend unavailable" Terminals state in web mode, CI-mirrored checks, and optional cloud services.

No application code was modified.

Verification

All checks run clean against a fresh npm install:

Check	Command	Result
Typecheck	npm run typecheck	pass
Tests	npm --prefix app run test	481 passed (85 files)
Release manifest	npm run test:release-manifest	pass
Build	npm run build	built in ~9s
Run	npm run jarvis	Vite serves :5173, HTTP 200
