pingqiuandClaude Opus 4.6 61e9408261 fix: separate stable ReplicaID from Endpoint in registry
Registry is now keyed by stable ReplicaID, not by address.
DataAddr changes preserve sender identity — the core V2 invariant.

Changes:
- ReplicaAssignment{ReplicaID, Endpoint} replaces map[string]Endpoint
- AssignmentIntent.Replicas uses []ReplicaAssignment
- Registry.Reconcile takes []ReplicaAssignment
- Tests use stable IDs ("replica-1", "r1") independent of addresses

New test: ChangedDataAddr_PreservesSenderIdentity
- Same ReplicaID, different DataAddr (10.0.0.1 → 10.0.0.2)
- Sender pointer preserved, session invalidated, new session attached
- This is the exact V1/V1.5 regression that V2 must fix

doc.go: clarified Slice 1 core vs carried-forward files
