uv init --app should create main.py instead of hello.py

[kdheepak]

I've been using uv init --app a lot more recently because I've deploying a script using panel. I consistently rename hello.py to main.py.

I do think hello.py might a good beginner friendly name. I also think main.py would be equally obvious as to the fact that this is a script that is runnable. I think the following names would be all equally intuitive as an entrypoint.

• main.py
• {project_name}.py
• cli.py
• script.py
• entrypoint.py

The reasoning for this change is that I think uv should prefer that commonly used commands were optimized for long term or frequent users, while still being beginner friendly.

Thanks! I think this is a duplicate of #7782 which is addressed by #10369 (in the next minor release).
