Teknium 14cf2d85ca fix(display): guard isatty() against closed streams via _is_tty property (#3056) ...

In gateway/Telegram mode, the stdout fd can be closed by executor
thread cleanup. KawaiiSpinner.stop() called isatty() on the closed fd,
raising ValueError and masking the original error.

Instead of a point fix, add a _is_tty property that centralizes the
closed-stream guard — both _animate() and stop() now use it. Follows
the same (ValueError, OSError) pattern already in _write().

Inspired by PR #2632 by bot-deo88.
