perf(jest): Mock root ECharts imports#120049

Conversation
The existing mapper only catches ECharts subpaths, so root imports still load and transform the full package. Match the root export too and fill in the small API surface tests use.\n\nThe focused chart suite drops from a 4.530s median to 4.125s with Jest's cache disabled, about 9% faster.\n\nCo-Authored-By: Codex <noreply@openai.com>

The ECharts Jest mapper only matched subpaths, so root imports still loaded and transformed the real package. Match both the package root and subpaths to the lightweight mock, and expose the small root API surface tests use.
Benchmarking
useChartXRangeSelection.spec.tsxover five cache-disabled runs:This helps any Jest suite that reaches a root ECharts import by avoiding the real module work.
