Add auto-port dev script for worktree support

- Add scripts/dev.sh that finds available ports for daemon (6767+) and Metro (8081+)
- Runs both services via concurrently with colored output
- Sets PASEO_CORS_ORIGINS dynamically for the Metro port
- Sets EXPO_PUBLIC_DAEMONS to auto-configure app with daemon endpoint
- Add get-port-cli and concurrently as dev dependencies
- Rename npm run dev to use the script, add dev:server for daemon-only
