jedarden 963059c370 Phase 1 (miroir-cdo): Core Routing — Final verification complete 
## Summary

Verified that all Phase 1 acceptance criteria are met:

### Router Correctness (router.rs)
- ✅ Rendezvous determinism across 1000 runs
- ✅ Minimal reshuffling on node add/remove
- ✅ Uniform distribution (64 shards, 3 nodes, RF=1 → 18–26 per node)
- ✅ RF=2 placement stability
- ✅ write_targets returns RG × RF nodes
- ✅ query_group distributes evenly
- ✅ covering_set returns one node per shard with replica rotation
- ✅ shard_for_key uses seed 0 (matches Meilisearch Enterprise)

### Result Merger (merger.rs)
- ✅ Global sort by _rankingScore
- ✅ Offset/limit applied after merge
- ✅ Conditional _rankingScore stripping
- ✅ _miroir_* reserved fields always stripped
- ✅ Facet counts summed across shards
- ✅ estimatedTotalHits summed
- ✅ processingTimeMs = max across shards

### Coverage
- ✅ miroir-core: 91.80% line coverage (exceeds 90% requirement)
  - router.rs: 96.20%
  - topology.rs: 100.00%
  - scatter.rs: 100.00%
  - merger.rs: 94.67%

### Test Results
All 151 tests pass.
