fix(cli): release SessionDB handles when deleting a profile

delete_profile already force-closes holographic memory_store.db in this
process, but the shared SessionDB registry kept state.db open. Recreate
then failed with a replaced/locked database. Close every shared handle
under the doomed directory, same contract as MemoryStore.release_all_under.
