Walkthrough

This PR introduces a new "test type" grouping dimension across the dashboard. It adds an aggregation utility, updates multiple chart and filter components to support test type grouping, implements formatting for category labels, and includes comprehensive test coverage for the new functionality.

Changes

Cohort / File(s)	Summary
Core Aggregation apps/dashboard/src/lib/aggregations-core.ts	Added new groupByTestType() utility function that groups MatrixItemResult items by their category field, with fallback to "uncategorized".
Chart Components apps/dashboard/src/components/charts/composite-score-chart.tsx, apps/dashboard/src/components/charts/pass-rate-chart.tsx	Added test type tabs and grouping to both composite and pass-rate charts; extended onDimensionClick callback to include "testType" dimension; updated component signatures to handle test type grouping and formatting.
Dimension Dialog apps/dashboard/src/components/run-detail/dimension-detail-dialog.tsx	Extended DimensionType to include testType; added filtering and formatting for test type dimension; added test type sub-dimension breakdown with optional name formatting callback.
Leaderboard Filtering apps/dashboard/src/components/leaderboard/leaderboard-filters.ts, apps/dashboard/src/components/leaderboard/leaderboard-page.tsx	Extended FilterState interface and initialization to include testType field; implemented test type filter logic deriving type from item.category; added test type filter dropdown to leaderboard UI with adjusted grid layout.
Utilities & Formatting apps/dashboard/src/lib/utils.ts	Added new formatTestCategoryLabel() function that converts category slugs (e.g., "computer-use" → "Computer Use") to user-readable labels.
Tooltip Updates apps/dashboard/src/lib/tooltip-content.ts	Updated composite chart tooltip text to mention "test types" alongside existing dimensions.
Test Coverage test/dashboard-test-type.test.ts	Added comprehensive test suite with fixture builders validating test type grouping computations and leaderboard filtering behavior.
