Fix public simulator and complete missed-call demo flow

[DevCalebR]

Summary

• replace the env-gated public /simulator route with a self-contained browser-only demo
• run the full current missed-call qualification flow through service, urgency, name/location, callback time, and confirmation
• show the completed lead summary and owner alert preview with safe masked demo data

Root cause

The public simulator page still depended on the legacy backend simulator path, which expected demo-business environment configuration and old server actions. That caused the unconfigured fallback state in production and let the simulated conversation drift behind the real missed-call qualification flow.

What changed

• added a client-side public simulator experience and pure state helpers for the public route
• shared the production SMS copy and deterministic intake parsing between the real flow and the simulator to reduce drift
• kept the legacy env-backed simulator helpers separate for internal/demo-business use
• updated README and production env docs to reflect that /simulator is self-contained by default
• added coverage for the public simulator flow, isolation, and route behavior

Validation

• npx tsx --test tests/public-simulator.test.ts tests/simulator-route.test.ts tests/public-demo-route.test.ts tests/simulator-isolation.test.ts
• npm run typecheck
• npm run lint
• npm run test
• npm run build
• browser verification on http://localhost:3000/simulator through the full demo flow
