add hidden race checks for real and interpolated frames, including runs limited to four cpu cores. uses the renderer changes in patchzyy/aurora-wiicompiled#6.
Summary by CodeRabbit
New Features
Added hidden-window mode for boot races while keeping audio enabled. Hidden and headless modes require a boot race; headless mode continues to silence audio. Fatal popups are suppressed in both modes.
Added per-frame timing traces and a command-line analyzer for reviewing stutter and presentation cadence, with configurable warmup and timing anchors.
Added a Windows benchmark runner with configurable test runs and per-run and aggregate results. It can flag display-limited interpolation targets.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.

Walkthrough
The runtime now emits benchmark readiness and frame timing data for hidden CPU races. A new analyzer evaluates frame-trace CSV files, and a Windows benchmark runner executes configured test matrices and records results.
The runtime accepts --hidden for boot races, reports readiness once in the CPU-driven branch, and sends elapsed-frame and wait durations to Aurora. Frame tracing enables timing collection without performance-log output. The subproject reference and .NET workflow versions are updated.
Trace parsing and stutter analysis runtime/tools/analyze_stutters.py, runtime/tools/test_analyze_stutters.py
The analyzer validates trace files, selects timing anchors, calculates cadence and stutter evidence, and reports interpolation status. Tests cover trace formats, timing anchors, display limits, and analysis results.
Benchmark matrix setup and execution runtime/tools/benchmark_stutters.py, runtime/tools/test_benchmark_stutters.py
The Windows runner validates inputs, prepares isolated benchmark cases, launches hidden races, analyzes recorded traces, and writes case and aggregate results. Tests cover configuration generation, validation, readiness polling, and process shutdown.

Benchmarks can omit the final fraction of a second of frame data. The change remains mergeable with that limitation understood.

`ShowRuntimeFatalPopup` and update its suppression check to skip the popup when
either headless or hidden mode is active. Preserve the existing fatal-popup
behavior for visible, non-headless runs.

Reject incomplete traces before writing benchmark results.
The timeout path stops the game before analyze(). analyze() can report lost samples or a truncated final row, while the current gates still pass when only a small tail is missing. The runner then persists stutter statistics that can omit a stutter at the end of the measurement.
Suggested fix
result = analyze(trace, args.warmup, fps or 60)
+ if result["lost_trace_samples"] or result["truncated_final_row"]:+ raise RuntimeError(f"{label}: incomplete trace; see log")
log_text = (output / f"{label}.log").read_text(encoding="utf-8", errors="replace")
