fix: preserve partial benchmark failures in published results

[lukekarrys]

When only one of three benchmark runs succeeds, processing currently publishes its timing as an ordinary result and loses the failed exit codes. Preserve attempted, successful, and dropped counts plus original exit codes; label partial results in tables and every chart layout; and omit affected commands from rankings and daily history comparisons. Synthetic average rows retain partial warnings.

The schema additions are optional for historical compatibility. Existing survivor arrays and total-failure DNF sentinels remain readable, while partial CPU aggregates are omitted and a single survivor has no reported standard deviation. The registry raw-failure scan remains before processing, and post-processing speed comparisons exclude partial results.

Validation:

• 12 script tests pass, covering complete/partial/total failure, repeated processing, PM and registry chart output, historical compatibility, and raw-validation ordering.
• 5 app regression tests pass for labels, ranking exclusion, synthetic averages, and historical daily aggregation.
• Forced TypeScript check and Vite production build pass.
• Adds a Node 24 PR workflow to run the data tests and app build.
• Browser visual verification was unavailable because no browser was connected in this session.

Closes #153
