Fix panic in 'bd stats' when daemon is running (#69)

The statsCmd was not checking if a daemon client was available before
trying to access the store directly. When the daemon is running, store
is nil, causing a panic.

This fix adds a check for daemonClient and uses RPC to get statistics
when the daemon is available, falling back to direct store access only
when running in direct mode.
