Subject: [PATCH] fix(cli): suppress Windows pty resize race condition

Add global uncaught exception handler to suppress known race condition
in @lydell/node-pty where a deferred resize fires after the pty process
has already exited on Windows.

Tracking bug: https://github.com/microsoft/node-pty/issues/827
