Remove `**...**` emphasis markers from inline comments and JSDoc blocks across
auth and chat components, machine mappers, and quota helpers. These are
plain code comments, not rendered markdown, so the bold syntax was noise.
Files touched:
- src/app/auth/components/auth-screen.tsx
- src/app/chat/components/chat-header.tsx
- src/app/chat/components/chat-screen.tsx
- chat machine mapper / quota helpers
No functional or behavioral changes.
Comment out `src/router/index.ts` and `src/router/proxy.ts` to temporarily
disable the Next.js 16 proxy (auth-driven redirects) and router re-exports.
This effectively turns off the centralized route guard logic and stops the
proxy from intercepting requests until further iteration.
