refactor(commands): cache slash-command wrappers in private fields

Browse Source 
TearDownCommands attached the same instance via re-Register with identical
args, which was functionally a no-op but masked a latent bug if Description
or ShowInHelp ever diverged between Setup and Teardown. Hold the wrapper
instances as nullable fields so Teardown can detach the live registration
directly. Mirrors the cached-wrapper pattern in ChatLogWindow.
