…waits - Resume saveCompletionContinuation in MainContentCoordinator.deinit to prevent permanent hang if coordinator deallocates during save - Support multiple concurrent waitUntilReady() callers in WindowOpener by using an array of continuations instead of a single optional

Summary
Two fixes from the performance audit (Tier 1 critical items):
saveCompletionContinuation hang —
MainContentCoordinator.deinitnow resumes the pending save continuation withfalsebefore cleanup. Previously, if the coordinator was deallocated mid-save (force close, SwiftUI view discard), the awaiting Task inMainContentCommandActions.closeAfterSave()would hang forever.WindowOpener concurrent waiters —
readyContinuation(singleCheckedContinuation?) replaced withreadyContinuations: [CheckedContinuation]. Multiple subsystems can now awaitwaitUntilReady()concurrently at cold launch without the second caller overwriting and orphaning the first caller's continuation.The third audit item (
usleepinAutoTOTPProvider) was re-assessed as correct — it runs on a dedicated detached thread, not the cooperative pool.Test plan
