Agent-driven kanban board for DeepSeek Harness

Key features

• Agent-driven kanban boards for DeepSeek Harness — one board per workspace, one task session per item.
• Boards live where your work lives
• One JSON file per workspace/.dsh-kanban-flow.json — schema-versioned, migrated automatically, corrupt files backed up before being reset.
• The sidebar icon and workspace-click behavior anchor on its sidebar markup (no per-row slot exists yet)
• The agent picks up, works, narrates every step in its own task session, and asks for review when it needs you.
