Merge branch 'main' into jaeone/refactor-errors-tab-selection

- Replace the two emphasis class constants with a selectionEmphasisClass(highlighted) helper and update all call sites
- Inline someNodeTypeInSelection at the card bindings instead of wrapper functions
- Extract assetNodeIdsWithError and derive selectionMatchedAssetNodeIds/errorNodeCount from it, dropping the imperative set-building
- Build selection-matched sets via map/filter instead of mutation
- Drop redundant highlighted=false prop defaults and template-only props from destructuring
- Trim justification comments; move e2e comments into expect messages
- Rename the pre-mount emphasis test to describe the collapse behavior it asserts
