Add production file logging with logrotate support

Browse Source 
Both control plane and host agent now write structured slog output to
$WRENN_DIR/logs/ in addition to stderr. Log level is configurable via
LOG_LEVEL env var (default: info). SIGHUP reopens the log file so
logrotate can rotate without copytruncate.
