Phase 1 — Core Routing: Additional test coverage and improvements
- Add edge case tests to scatter.rs (empty target shards, network error fallback, deadline propagation) - Add Clone derive to QueryCoalescer for improved async patterns - Update p43_node_drain test for new plan_search_scatter signature - Fix Response types in proxy search routes (use Body instead of opaque Response) - Minor import refactoring in middleware.rs All 145 Phase 1 tests passing (router: 20, topology: 35, scatter: 51, merger: 39) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
