## Upstream Issue Summary (denoland/deno#31890)

- Deno previously restricted TTY streams to file descriptors 0-2, which caused
Node compatibility crashes when packages created TTY streams on other fds.
- The fix adds an op to open TTY resources from any valid terminal fd by safely
duplicating the descriptor and validating it is a TTY.
- A JavaScript TTYStream wrapper now handles arbitrary fds, while ReadStream and
WriteStream keep the 0-2 fast paths for stdin/stdout/stderr.
