Why add_board_widget needs a policy

This tool creates a new board widget/column, which is a Write operation — it modifies the Kanban board configuration reversibly. It does not delete data (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or merely read data (Read). Severity is medium because misuse could clutter the board or affect team workflow, but the impact is localized to board UI and easily undone.

From the tool's definition Tool description states 'Add a widget (column) to a Kanban board' — this creates or modifies board structure by adding a new column.
