Move the pty master behind a small interface (Read/Write/Close/Resize), and push the actual startup into a platform-specific StartPty function in pkg/commands/oscommands. The Unix implementation still uses creack/pty; the Windows implementation is a stub that returns ErrPtyUnsupported, at which point newPtyTask falls back to a plain cmd task — matching the existing Windows behavior. The primitive lives in oscommands rather than pkg/gui because the cmd_obj_runner pty handler (also in oscommands) is going to consume it too, and tasks → oscommands is the existing dependency direction. Same observable behavior on every platform; this just carves out a seam for a real ConPTY implementation on Windows. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
