Add comprehensive integration tests for plan §8 requirements:
- Document round-trip: 1000 docs indexed and retrieved, verified distributed across ≥2 nodes
- Search covers all shards: 100 docs with unique keywords, each search returns 1 hit
- Facet aggregation: 100 docs across 3 colors, facet counts sum to 100
- Offset/limit paging: 50 docs, 5 pages of 10 match single limit=50 query
- Settings broadcast: synonyms propagated to all 3 nodes
- Task polling: 500 doc batch, poll until succeeded
- Node failure with RF=2: marked #[ignore], requires docker-compose-dev-rf2.yml
All tests use docker-compose-dev stack (3 Meilisearch nodes + Miroir).

Add comprehensive integration tests for Miroir with 3 Meilisearch nodes
via docker-compose. Tests cover:
- Document round-trip with distribution verification (1000 docs)
- Search covers all shards (100 docs with unique keywords)
- Facet aggregation across shards (100 docs, 3 colors)
- Offset/limit paging consistency (50 docs, 5×paged vs single)
- Settings broadcast to all nodes (synonyms test)
- Task polling for large batches (500 docs)
- Node failure with RF=2 (requires docker-compose-dev-rf2)
Also added integration test README with setup and running instructions.
Per plan §8: Integration tests validate end-to-end behavior including
document distribution, shard coverage, facet aggregation, paging, settings
broadcast, task polling, and node failure with RF=2.
