#424 made MemberRegistry.slots() re-read fleet: on every call, but only
roleForSlot was tested against a real reload. profileForSlot, isSlot and
nameForSlot all have the same live-read line and none was pinned — proved by
freezing each to a construction-time snapshot and watching the full suite
stay green.
Adds 4 tests to MemberRegistryLiveTest, each driving a real ConfigRef.reload()
against a @TempDir config file (never two frozen registries compared in
memory, which would test the constructor instead of the reload):
- profileForSlotReflectsAProfileChangedByReload
- isSlotStopsReportingASlotRemovedByReload / isSlotStartsReportingASlotAddedByReload
- nameForSlotReflectsANameChangedByReload
No production change. profileForSlot has no call site anywhere in src/main
yet, so there is no spawn-lifecycle seam to drive the test through beyond the
accessor itself.
