feat: add dev mode with DEV_ env prefix

Support dual configuration: PROXY_TOKEN/SERVER_URL for production,
DEV_PROXY_TOKEN/DEV_SERVER_URL for local development.

- npm start → production
- npm run start:dev → dev (PROXY_MODE=dev)
- npm run dev → dev with hot-reload
- Restore PTY auto-creation on sync_state for existing chats
