The status snapshot tore down on every management retry because
state.Status() blanks the status when an error is wrapped, and the
SubscribeStatus stream propagated that as FailedPrecondition. The UI
treated any stream error as "daemon not running" and flickered the tray
to Not running between retries.
Disconnect was also unresponsive: Down set Idle before the retry
goroutine exited, which then overwrote it with Set(Connecting) on the
next attempt; the backoff sleep (up to 15s) wasn't context-aware, so the
goroutine kept running long after actCancel.
- buildStatusResponse falls back to the underlying status (via new
state.CurrentStatus) instead of breaking the stream on wrapped errors.
- UI only flips to DaemonUnavailable on codes.Unavailable / non-status
errors, so a live daemon returning FailedPrecondition is not reported
as down.
- connect retry uses backoff.WithContext so actCancel interrupts the
inter-attempt sleep, and skips Wrap(err) when the dial fails due to
ctx cancellation.
- Down sets Idle after waiting for giveUpChan, so the retry goroutine
can no longer race the disconnect.
- Tray hides Connect during Connecting and keeps Disconnect enabled so
the user can abort an in-flight connection attempt.
