Changelog

When a dataset chart query fails with a binder or aggregation error,

the loader now sends a ChartQueryErrorMessage to the shell's

DatasetInsightOrchestrator for AI-assisted correction. The AI returns

a fixed chart config which is retried once. Recovery has a 15-second

timeout and only attempts one retry to prevent infinite loops.

Notes plugin version bump to 1.56.0.

All three sections' child items now use 22px left margin so their icons

line up vertically with the section header icons (chevron 14px + gap 4px

+ button padding 12px = 30px from edge, minus 8px ListBox margin = 22px).

Datasets header now matches Views and AI Generated with a collapsible

button, chevron, bar-chart icon, bold title, and count badge. Chevrons

are wrapped in a fixed 14x14 Border so rotation doesn't shift their

visual position. The star-fill role cascades: AI Generated > Views >

Datasets, so the last expanded section always fills remaining space.

When sections collapse, the remaining expanded section (or Datasets) now

takes over the Star (*) fill role so there's no unallocated empty space.

Datasets row becomes Star when both Views and AI Generated are collapsed,

Views row becomes Star when only AI Generated is collapsed.

Views and AI Generated sections now properly shrink to header-only height

when collapsed instead of keeping the full row height with empty space.

The code-behind subscribes to IsViewsExpanded/IsAiGeneratedExpanded

property changes and toggles the Grid RowDefinition between pixel/star

height and Auto. Adjacent GridSplitters are hidden when sections collapse.
