feat: Add startup banner to CLI

[hduoc2003]

Added a bold ASCII banner to neptune-core, neptune-cli, and neptune-dashboard for improved visual identity on startup.

Lovely contribution, thank you :-)

I left some minor change requests inline.

About the neptune-banner.txt asset file, could you explain to me how it works? What I'm concerned about is shipping the executable with a text file, and having that executable crash if the text file is not present. However, if the content of this txt file ends up as part of the executable, then it's all good in my book.

can we wait until crate separation PR bcs this would probably cause too many annoying conflicts?

It actually gets embedded into the executable at build time, so it doesn’t rely on an external file at runtime sir.

I am getting identical pictures if I change the line

println!("{}", NEPTUNE_BANNER.fg_rgb::<255, 255, 255>().bold());

into

println!("{}", NEPTUNE_BANNER);

.

At this point, new dependency owo-colors is not used. Is there something I'm not seeing? Does something break if we drop it? I prefer fewer dependencies to begin with but if there is not even any difference, there's a very easy case for dropping it ...

Here is the result, sir. It's just ... not bold :)

Right, so bold makes a difference. That leaves the main question, which is: is owo-colors necessary?

owo-colors is a Rust crate for styling terminal output (colors, bold, underline, etc.). We need it for bold text to work sir.
