Issue for this PR
Closes #42225
Type of change
What does this PR do?
OpenTUI reads
process.stdout.columnsandprocess.stdout.rowswhen handlingSIGWINCH. In affected PTY hosts, Bun can leave those cached values stale until the stream refreshes its window size.This change refreshes the TTY dimensions before OpenTUI receives the resize signal. It performs one initial refresh, installs the listener ahead of the renderer listener, and removes it when the TUI scope closes.
How did you verify your code works?

Not included. The failure is specific to live terminal resizing; the signal ordering is covered by a focused regression test and was also verified interactively in tmux.
