`openenv validate` falsely fails when `main()` is called with arguments

[pvs333]

Description

openenv validate reports the following issue even when main() is properly
defined and callable:

server/app.py main() function not callable (missing if __name__ == '__main__')

Root Cause

In src/openenv/cli/_validation.py, the check is:

if "__name__" not in app_content or "main()" not in app_content:
    issues.append("server/app.py main() function not callable...")

This is a plain string search for "main()". If main() is called with
arguments like main(port=args.port), the string "main()" never appears
and the check fails — even though the function is perfectly callable.

Steps to Reproduce

1. Create a server/app.py with a valid main() function
2. Call it with arguments in the __main__ block:

   if __name__ == "__main__":
       main(port=8000)

3. Run openenv validate
4. Observe false failure

Expected Behavior?

The check should pass as long as a main() exists and if __name__ == "__main__" is present, regardless of how main() is called.

Workaround

Adding # main() as a comment in app.py passes the string check but is obviously not a real fix.

Environment

• openenv-core version: 0.2.3.dev0
• Python: 3.14
