Build safe public simulator demo

[DevCalebR]

Summary

• polish the public simulator sales flow with a single pilot-focused final CTA and clearer /demo vs /simulator positioning
• add a simple in-repo app icon so public pages no longer fall back to a missing favicon request
• document the local Clerk localhost-origin limitation and update simulator docs to reflect the new self-contained public flow

Why

The old public simulator looked broken because it exposed setup-dependent messaging and felt unfinished. The first pass fixed the safety and interaction model; this cleanup pass makes the sales flow clearer, removes the favicon noise, and leaves the remaining localhost Clerk issue clearly documented instead of hidden.

Safety confirmation

• no real SMS is sent from /simulator
• no Twilio calls are made from /simulator
• no login is required
• public simulator traffic stays inside the browser demo flow and does not enter customer workflows

Validation

• focused simulator tests: npx tsx --test tests/public-demo-route.test.ts tests/public-simulator-flow.test.ts tests/simulator-isolation.test.ts tests/simulator-route.test.ts tests/favicon-route.test.ts
• npm run typecheck
• npm run lint
• npm run test
• npm run build
• browser smoke: loaded /simulator, completed a run with quick + typed replies, confirmed owner alert preview, reset/replay, mobile layout, and favicon behavior

Remaining known issues

• local browser console still shows Clerk origin errors when localhost is pointed at production-domain-restricted Clerk keys; this is now documented in .env.example and README.md
