Implements elastic cluster operations:
- Rebalancer with node add/remove/drain and replica group operations
- HttpMigrationExecutor for HTTP-based document migration between nodes
- MigrationCoordinator with quiesce-then-verify cutover sequence
- Full HTTP admin API (POST /_miroir/nodes, DELETE /_miroir/nodes/{id}, etc.)
- miroir-ctl commands for all topology operations
- 8 chaos tests covering all topology change scenarios
Definition of Done — ALL CHECKED ✅:
- [x] Chaos test: add a node mid-indexing — every doc remains readable; no duplicates
- [x] Chaos test: drain a node while queries in flight — zero client-visible failures
- [x] Chaos test: add a replica group while queries in flight — existing groups unaffected
- [x] Rebalance of a 3→4 node cluster moves ≤ 2×(1/4) of docs
- [x] Restart a killed node mid-rebalance — rebalance pauses + resumes; no data loss
