0.16.0 — Compact Mode · Kandown changelog

Added: Compact board density — column density can now use a space-saving layout where empty columns collapse into a thin strip (100px wide) or stack vertically when multiple consecutive columns are empty. Normal columns keep their full width. In compact mode the empty-column cards show only an icon + name, minimizing wasted space for boards with many columns.
Added: isEmptyCompact column prop — Column.tsx now renders a minimal icon+label placeholder when there are no tasks and the compact density is active.
Changed: Board layout refactored through columnGroups — the board now groups consecutive empty columns into compact-single (one column strip) or compact-stack (vertical stack), improving density for task-heavy boards.
Removed: Task placeholder t119 — removed unfinished placeholder task file.
