Notable features

Added explicit extent examples and tests for chart-level xExtent/yExtent pass-through

Full changelog

Added

Added explicit extent examples and tests covering chart-level xExtent/yExtent pass-through.

Fixed

Fixed yExtent handling so explicit user bounds continue to control the rendered domain instead of being overridden by envelope-derived extents.
Fixed realtime heatmap tooltip metadata so bin-center values are available and agg="sum" tooltips report summed values.
