   ## Summary
   
   Documents the UNIX setuid-on-exec `sudo` helper: kernel raises euid from the 
file owner on exec, userspace checks the password, then `setresuid`/`execvp` 
run the command. Adds an NSH `sudo` command page and a short setuid-on-exec 
note in the user-identity guide. Companion apps change: 
https://github.com/apache/nuttx-apps/pull/3728
   
   ## Impact
   
   Documentation only. No kernel API or runtime change. Describes 
`CONFIG_SYSTEM_SUDO` as an application, not an NSH builtin.
   
   ## Testing
   
   Host: Linux x86_64 (WSL2), gcc 13.3.0. Target: `sim:login` with 
`CONFIG_SYSTEM_SUDO=y` (apps PR 3728). Docs built as part of the same tree; 
runtime shows the setuid helper installed:
   
   ```
   login: root
   password:
   User Logged-in!
   
   NuttShell (NSH) NuttX-13.0.0
   nsh# id
   uid=0(root) gid=0(root)
   nsh# ls -l /bin/sudo
    -rwsr-xr-x    root    root           0 /bin/sudo
   ```
