- New task_blockers join table (many-to-many, cross-project)
- Cycle detection prevents circular dependencies
- GET /api/tasks/{id}/blockers and /blocking endpoints
- POST/DELETE /api/tasks/{id}/blockers/{blocker_id}
- GET /api/actionable — all non-done tasks with no incomplete blockers
- BlockerPanel.jsx — search & manage blockers per task (via task menu)
- ActionableView.jsx — "what can I do right now?" dashboard grouped by project
- "Now" button in nav header routes to actionable view
- migrate_add_blockers.py migration script for existing databases
