Subject: [PATCH] fix: add (require :sb-posix) before SIGWINCH handler

sb-posix is a built-in SBCL contrib, available via require.
Without it, sb-posix:sigwinch causes a reader error and the
eval-when for the SIGWINCH handler never executes, making
*terminal-resized-p* always nil and resize detection broken.
