Context

Implement pluggable task assignment strategies per spec section 6.4. Different situations call for different assignment approaches — sometimes a human specifies who should do the work, sometimes the system should auto-assign based on skills or workload.

Acceptance Criteria

Strategy Interface

• Pluggable strategy interface (`TaskAssignmentStrategy` abstract class)
• Strategy selection configurable per company or per project

Implemented Strategies (at least 3)

• Manual — explicit assignment by human or manager agent
• Role-based — match task requirements to agent skills/role
• Load-balanced — distribute tasks evenly across available agents
• Cost-optimized — assign to cheapest capable agent (stretch goal)
• Hierarchical — follow management chain for delegation (stretch goal)

Testing

• Unit tests for each implemented strategy
• Test that strategy interface is properly abstracted (easy to add new strategies)

Dependencies

• Depends on task decomposition and routing engine (Implement task decomposition and routing engine #14)
