Separate platform-dependent code into build-tagged files: - process_unix.go / process_windows.go: isProcessRunning() implementation - signals_unix.go / signals_windows.go: daemon signal handling (Windows lacks SIGUSR1) Windows implementation uses windows.OpenProcess with PROCESS_QUERY_LIMITED_INFORMATION and checks exit code against STILL_ACTIVE (259).
