Do not allow hops before the stored budget loads.

If a fresh client has an exhausted budget file, startUp() can return before this task runs. During that interval, cachedMillisUntilHopAllowed() treats the empty memory store as a full budget. A logged-in caller can therefore hop despite the stored limit. Keep hop requests unavailable until persistTo() completes, without blocking the Swing thread.

around lines 188 - 189:
Update the startup flow in MicrobotPlugin around the executor task that calls
HopBudget.persistTo so hop requests remain unavailable until that operation
completes; make cachedMillisUntilHopAllowed() or the hop-request path honor the
load-ready state, without blocking the Swing thread.
