Changed

• Task tag field renamed to tags across all layers: parser, REST API, MCP tools, cache, CSV export/import, and frontend; existing task files must be migrated with find board -name "*.md" -exec sed -i 's/^tag:/tags:/' {} \;

Fixed

• Settings: tag names containing spaces are now rejected; placeholder updated to “New tag name (no spaces)”

Added

• MCP update_task: new fields effort, blocked_by, planned_start, planned_end so task scheduling and dependency tracking can be set via MCP
• MCP list_tasks: new completed boolean filter to exclude or isolate completed tasks without fetching everything
• MCP create_meeting and update_meeting: actions array field so meeting action items can be written via MCP (each action: description, owner, due, status)
