🟡 Changes recommended

Batch cancellation is currently reported as “completed” (misleading UI/state), and a couple of smaller correctness/clarity issues should be addressed before merge.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Adds an initial “Batch mode” workflow to run selected benchmark profiles across multiple drives, track progress, and review historical batch runs via a new bottom-pane reports tab.

Changes:

• Introduces Batch UI (setup → running → results) plus Batch Reports history tab and tab constants.
• Persists batch grouping via a batchId on Benchmark and adds queries to load batch history.
• Wires theme/palette updates so the batch comparison chart matches the active UI theme.
