Title:
  Sudo-rs panics executing shell script without execute permission

Status in rust-sudo-rs package in Ubuntu:
  Confirmed

Bug description:
  My Ubuntu Budgie install was updated to Ubuntu 25.10 last week which
  replaced sudo with the rust sudo-rs version 0.2.8.

  Today I was executing a bash script with sudo and forgot to grant the
  script execute permission. Not a big problem however the response from
  sudo-rs was a panic, rather than a gracefully handled error message.

  I retested with a very simple script and the panic is 100%
  reproducible.

  Is this the same bug as:
  https://github.com/trifectatechfoundation/sudo-rs/pull/1298

  sudo ./test

  #!/bin/bash
  sudo apt update

  thread ‘main’ panicked at src/exec/use_pty/monitor.rs:283:45:
  internal error: entered unreachable code
  note: run with RUST_BACKTRACE=1 environment variable to display a backtrace
  sudo-rs: cannot execute ‘/home/REDACTED/test’: Permission denied (os error 13)
