feat: add dev-daemon target for background development mode
Add a new make dev-daemon target that allows running DeerFlow services in background mode without keeping the terminal connection. Following the pattern of PR #1042, the implementation uses a dedicated shell script (scripts/start-daemon.sh) for better maintainability. - Create scripts/start-daemon.sh for daemon mode startup - Add dev-daemon target to Makefile - Each service writes logs to separate files (langgraph, gateway, frontend, nginx) - Services can be stopped with make stop - Use nohup for proper daemon process detachment - Add cleanup on failure when services fail to start - Use more specific pkill pattern to avoid killing unrelated nginx processes
