-Fix critical memory leak in VPivottableUi component (#270)
-
-- Remove deep watch that created thousands of property watchers (80% of memory leak)
-- Replace computed PivotData with shallowRef to prevent instance recreation on every access
-- Add proper cleanup in onUnmounted lifecycle hook
-- Results: 94% memory reduction (881MB → 53MB after 1000 refreshes)
-- Fixes #270: Memory continuously increases when refreshing pivot chart
