Pull request overview

Fixes T1306434: the new grid_core (CardView) did not raise onOptionChanged when column properties were updated. The PR wires column mutations through the component's _notifyOptionChanged, while preventing the resulting event from being re-processed by the internal options-sync handler.

Changes:

• Added notifyColumnOptionChanged on OptionsController that calls component._notifyOptionChanged and uses a _skipProcessingColumnsChange flag to bypass the internal onOptionChangedHandler for the in-flight path.
• In ColumnsController.columnOption and updateColumns, compute previous/new values and emit columns[i].<option> change notifications via the new helper, guarded by equalByValue.
• Introduced IGNORE_COLUMN_OPTION_NAMES to suppress notifications for internal-only column fields (visibleWidth, bestFitWidth, bufferedFilterValue, selector).
