• #12025 d06ad09 Thanks @petebacondarwin! - Fix potential EBADF error when restarting workerd process

  Previously, when the workerd process was restarted (e.g., via setOptions() or Vite server restart), the stdio pipes from the previous process were not explicitly destroyed. This could lead to EBADF (Bad File Descriptor) errors during spawn on some systems.

  The Runtime#dispose() method now explicitly destroys all stdio streams (stdin, stdout, stderr, and the control pipe) before killing the process to ensure file descriptors are properly released.
