Add sim infrastructure for registry testing:
- Extend DistributionSnapshot with registry_size, registry_tombstone_count
- Add SimAction enum (RegisterName, RegisterNameWithActor, UnregisterName)
- Add action_schedule to DistributionSimConfig for mid-sim registry ops
- Add run_simulation_with_nodes() returning node references for assertions
- Add property checks: registry_propagation, registry_tombstones, etc.
6 registry sim tests:
- registry_name_converges_across_cluster (PASS)
- split_brain_naming_converges_after_partition_heals (IGNORED — bug)
- tombstone_propagates_when_name_owner_dies (IGNORED — bug)
- rapid_re_registration_converges_to_latest (PASS)
- simultaneous_registration_converges_deterministically (PASS)
- multiple_names_from_different_nodes_all_propagate (PASS)
BUG FOUND: SwimProbe::check_suspicion_timeouts() calls
members.declare_dead() internally before SwimNode::translate_probe_actions()
processes the DeclareDead action, so the second declare_dead() returns false
and MembershipChanged{Dead} is never emitted. This silently breaks all
death-related side effects: RT cleanup, cache invalidation, repair queue
population, and registry tombstoning.
