Replace the monolithic useQueryToolData composable and nested Vue component tree
with a modular architecture: useLotResolve, useLotLineage, useLotDetail, and
useEquipmentQuery. Introduce ECharts TreeChart (LR orthogonal layout) for lot
lineage visualization with multi-select support, subtree expansion, zoom/pan,
and serial number normalization. Add unified LineageEngine backend with split
descendant traversal and leaf serial number queries. Archive the query-tool-rewrite
openspec change and sync delta specs to main.
