Reserves `--help` for each mix task and showing bad args error with its helper

Hello,

As we discussed on Discord, I think it would be great if `Igniter` reserves the `--help`s option and provides a display similar to mix help task.
This approach can help prevent mistakes for users of the `CLI,` especially those coming from **non-Elixir** stacks.

---
Another improvement that I believe can enhance the task is displaying a helper specific to each argument. For instance, if an argument is entered incorrectly, the task could show an error like:

```
** (Mix) Could not invoke task "mishka.ui.gen.component": 1 error found!
--color : Missing argument of type string
```

However, in a library like Clap (built on Rust), the usage of that option is also displayed. For example:

```
curl [options / URLs]
or
--alt-svc
or
Usage: color [OPTIONS]
```

This approach provides users with clear guidance on how to correctly use the options, similar to how it's presented in Unix-style commands.

---

By the way, since Igniter's strength lies in generating initial templates and providing a very intuitive structure, I believe that, in addition to argument definitions, composing other tasks, and similar features, it would be beneficial to include the version in its map. This way, the `--version` option could also be reserved automatically.

Of course, this is more of a personal suggestion, but I think it could add a nice touch to the tool's usability.

Thank you in advance

Start by reviewing Igniter's CLI entry point, task argument definitions, task composition, and version map. Clarify whether the scope includes reserved --help, argument-specific errors with usage, and automatic --version handling, then define tests and acceptance criteria for each behavior.
