Two problems prevented reliable recovery after a persistent overflow:
1. Restart storm: once read_error_streak >= 3, every subsequent read
failure triggered a deactivate/activate cycle, potentially preventing
the hardware from stabilising. Fix: after a successful restart, reset
read_error_streak to 1 so the stream gets 2 more failures before the
next restart attempt.
2. Stuck-deactivated stream: if activate() failed after overflow, the
stream was left deactivated. Subsequent reads returned non-overflow
errors which handle_read_error ignored (Ok(false)), so the stream was
never reactivated. Fix: add a high-streak fallback (>= 10 consecutive
errors of any kind) that also attempts a full deactivate/activate
restart, covering the stuck-deactivated case.
