test(phase3): add comprehensive tests for multi-agent coordination

Protocol tests (16):
- AgentRequest/AgentResponse serialization
- DelegationIntent and DelegationReason validation
- CoordinationResult aggregation
- Error type tests

Coordination tests (14):
- Engine initialization and agent availability
- Delegation execution (success, error, timeout)
- Multi-intent coordination
- Streaming delegation

Librarian tests (42):
- Library-desk client (all endpoints)
- Wiki operations (search, get, create, update)
- Smart-create with HybridRAG
- Capability registration
- Response model validation

Total: 72 new tests, all passing
