Mirrors the alpha_train CLI flag (--kernel-step-trace <path>) into fxt-backtest. The PerceptionTrainerConfig already accepts the path; this commit just exposes the CLI surface and propagates through: fxt-backtest run --kernel-step-trace <path> -> BacktestHarnessConfig.kernel_step_trace_path -> PerceptionTrainerConfig.kernel_step_trace_path Sweep YAML gains a `kernel_step_trace: Option<PathBuf>` base field. Argo lob-backtest-sweep-template gains a `kernel-step-trace` workflow parameter (default disabled; when set, --features kernel-step-trace is passed to cargo build AND --kernel-step-trace to fxt-backtest). Gated behind the `kernel-step-trace` Cargo feature (matching alpha_train). When disabled (default), zero overhead. Enables per-step JSONL diagnostic emission from inference kernels -- needed for Smoke 2 deep-dive after sampling histograms (in parallel investigation) localize the per-horizon dynamics bottleneck.
