Return errors instead of log.Fatalf in lifecycle/cli_adaptor.go - #12

log.Fatalf calls os.Exit(1) directly, which kills the whole harness process on a single trial's command failure instead of letting the orchestrator record the trial as failed and move on. Each CLI* helper here already returns (StageResult, error) as part of its signature, so no caller changes were needed: the fatal calls are replaced with returning the underlying error wrapped with fmt.Errorf, matching the error-wrapping style already used elsewhere in the codebase (e.g. internal/runtime/storage/adapter.go's getOrPullImage). log.Printf calls that were already non-fatal (e.g. best-effort stop/ cleanup logging) are left as-is.

Description
Part of #10 (a single failed trial currently kills the entire benchmark harness process via log.Fatalf). This PR covers just
internal/runtime/lifecycle/cli_adaptor.go: replaces its 7log.Fatalfcalls with wrapped errors, since every affected method already returns(StageResult, error)-- no signature/caller changes needed.Issues Resolved
Updates #10 (one of four small PRs against this issue, one per file -- not closing it alone)
Testing
go build,go vet,gofmt -l,go test ./...all clean.
