## Context
This commit adds the supporting infrastructure that makes the assign
feature work end-to-end.
## Components Added/Modified
### SmartDag
- Main view component for graph-based task management
- Integrates TaskCardGrid and WorkflowGraph
- Has 'Assign' mode toggle button
- Passes archetypes and assignMode to WorkflowGraph
- Manages filter state (hideClosed, sortReadyFirst, etc.)
### useGraphAnalysis Hook
- Extracted graph analysis logic for reuse
- Returns: actionableNodeIds, cycleNodeIdSet, blockerTooltipMap, etc.
- Used by both SmartDag and AssignmentPanel
- Ensures consistent 'actionable' definition across components
### UnifiedShell
- Added assignMode state
- Added selectedAssignIssue state
- Renders AssignmentPanel when in graph view + assign mode
- Wires up onAssignModeChange and onSelectedIssueChange callbacks
## Design Philosophy
- Shared hook means single source of truth for 'actionable'
- Clean separation between view (SmartDag) and sidebar (AssignmentPanel)
- URL state preserved for navigation
## Test Coverage
- SmartDag tests: 12 tests covering buttons, callbacks, imports
- useGraphAnalysis tests: 6 tests covering cycle detection, blockers
- UnifiedShell tests: 9 tests covering state and rendering
## The Feature Request
User wanted an enhanced sidebar panel showing:
- Tasks needing agents (ready but unassigned)
- Pre-assigned tasks waiting to start
- Active workers on current epic
## Design Collaboration
We discussed what each section should show:
1. **Needs Agent**: Actionable tasks (no blockers) without agent: label
2. **Pre-assigned**: Tasks with agent: label, not yet in_progress
3. **Squad Roster**: in_progress tasks with assignee
## Technical Implementation
- Uses useGraphAnalysis hook for actionableNodeIds
- Helper functions: hasAgentLabel(), getAgentLabels(), extractArchetypeIdFromLabel()
- Quick assign dropdown on each 'Needs Agent' item
- Archetype badges shown on 'Pre-assigned' items
## UI/UX Decisions
- Each section has count badge in header
- Max-height with scroll for each section
- Consistent styling with existing panel patterns
- Uses CSS variables for theming
## Test Coverage
- Added assignment-panel-sections.test.tsx with 5 TDD tests
- Tests verify: useGraphAnalysis import, section headers, filtering logic

## The Collaboration Story
User requested ability to assign agent archetypes to tasks directly from
graph nodes. This was the core UI feature request.
## Design Decisions Made Together
1. **Placement**: We decided to put the assign UI at the bottom of the card
to not interfere with existing status/badges display
2. **Pattern**: Used Radix dropdown-menu (already in project) for consistency
3. **Visual feedback**: Added loading spinner during API calls, success/error
messages that auto-dismiss
4. **Closed tasks**: Excluded closed tasks from assignment (logical constraint)
## Issues We Encountered
- Initially only added POST handler for assignment
- User pointed out we needed DELETE for unassign - added that
- The unassign button (X) needed to call DELETE not POST
## API Changes
- Added DELETE handler to /api/swarm/prep for removing agent assignments
- Uses 'bd label remove' under the hood
## What the UI Shows
- Dropdown with available archetypes
- Badge showing assigned archetype name with color
- X button to unassign (on each badge)
- 'Assigned' label on already-assigned archetypes in dropdown
## Test Coverage
- Added graph-node-assign.test.tsx with 6 TDD tests

## Context
This is the foundation commit for the 'Assign Archetypes to Tasks' feature.
We needed a way to display which agents are assigned to tasks directly on
the graph nodes.
## Decision Process
- User wanted to see agent assignments on DAG nodes
- We discovered that labels (including 'agent:archetype-id' format) weren't
being passed through the WorkflowGraph component
- Added 'labels' and 'archetypes' to GraphNodeData interface
## What Changed
- WorkflowGraph now passes issue.labels to each node's data
- GraphNodeData interface updated to include labels: string[]
- Added archetypes prop for dropdown population
## Test Coverage
- Added graph-node-labels.test.tsx with 4 passing tests
