feat: edge case registry sim tests + GracefulLeave action
Cycle 2 tests:
- explicit_unregister_propagates_to_all_nodes
- re_registration_after_tombstone_succeeds
- all_names_tombstoned_when_owner_dies
- graceful_leave_tombstones_registry_names
- piggyback_contention_both_propagate
Also:
- Add GracefulLeave variant to SimAction enum
- Fix cluster_survives_brief_message_loss config (dead_reprobe + suspicion_timeout)
- Harden split_brain test config (suspicion_timeout=200 prevents cascading false deaths)

feat: registry sim tests — 4 pass, 2 ignored (SWIM death bug)
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.
