fix: 🐛 ensure process exits after copying project files

[blazeshomida]

• 🐛 Added process.exit(0) to cleanly terminate the Node.js process once project files are copied.
• ✅ Prevents hanging processes after file operations are complete.

Hi @blazeshomida

If the current code (without process.exit(0)) is not good for me, can I reproduce it?

[blazeshomida]

@yusukebe Sorry I'm not sure I understand the question. However, when running the cli without the process.exit(0) the process just hangs. I need to manually press ctrl+c to kill the process. If you run the cli currently (without the process.exit(0)) you'll see the script hang on completion.

Thank you for the response, and sorry for my bad explanation.

If you run the cli currently (without the process.exit(0)) you'll see the script hang on completion.

On my machine, this behavior does not occur, and it works well.

If your problem will be solved with this PR, it's okay to merge. But, I'd like to reproduce the problem in my environment. I think the process should be exited normally without intentionally doing process.exit(0).

I'm sorry, after more testing, I notice that the script is only hanging when using the deno run command. I tried running it with pnpm then picking the deno template and it works. I think the issue is with Deno and not Hono. I apologize. I thought that it was something simple, turn's out it wasn't 😅.

Feel free to close the PR without merging. It's my mistake.

I see! No problem. Closing this PR.

Hey @blazeshomida

Now reopened. Let's merge it to resolve this issue: honojs/hono#3528, though it's a Deno-side matter.
