Feature request: "DO NOT MODIFY THIS FILE" as comment

[rottmann]

Add an option to store the DO NOT MODIFY THIS FILE header as a comment in a front matter block

example

---
# //////////////////////////////////////////////////////////////////////////////////////////////
# // DO NOT MODIFY THIS FILE                                                                  //
# // This file is automatically generated by ZenStack CLI and should not be manually updated. //
# // Source: db.zmodel · Generated: 2026-07-11                                                //
# //////////////////////////////////////////////////////////////////////////////////////////////
---

So it does not appear in the front end documenation page.
