fix: increase sleep time

- PID file failures now prevent service start instead of logging and continuing
- Status() methods use PID-based health checks instead of returning empty string
- NewResourceManager returns error instead of silently defaulting to 8GB
- Crash recovery re-allocates resources before relaunch
- restoreInstances stops after failed resource allocation
- Cluster manager bind errors propagated to Start()
- NATS disconnect/reconnect logged at Warn level
- VPC CIDR fallback logs warning about overbroad rule
- vpcd respond() handles json.Marshal failure
- Network cleanup failures logged instead of silently discarded
- fmt.Println replaced with slog.Debug in NATS service
- Signature mismatch no longer logs expected signature
- extractDiskImagePath uses errors.Is for EOF
- validateDiskImagePath checks file command error
- os.Stat uncommented in admin image import
- net.SplitHostPort errors checked
- Gateway response write errors logged
- vpcd OVN NB address uses leader IP on non-primary nodes
- Release workflow parallelized with native arm64 runner
