test: add routing integration tests for Phase 2 test requirements
9 tests covering the complete multi-agent routing flow:
- Single-intent routing to each agent (order_lookup, order_actions, discount, fallback)
- Multi-intent routing hint injection for sequential execution
- Ambiguity detection skips graph and returns clarification
- Low confidence threshold triggers ambiguity
- No-classifier fallback to supervisor prompt routing
Fills Phase 2 test requirement for integration-level routing coverage.
Total: 197 tests, 92.60% coverage.
