Minor typo fixing and code refactoring

[tensorush]

Hi! Great work with this TUI library!

I'd like to contribute these fixes:

• Added standard .gitattributes file for Zig projects.
• Reworked build.zig a little, hopefully it's a bit clearer. Also, now zig build will run all steps.
• outer: while in examples was redundant since there's only one loop to break from. switch expressions don't allow breaking from them, so breaking is only for loops, i.e. while and for.
• When returning a struct instance from a function, the compiler infers the return type from function signature, so instead of return MyType{...}; , it's more idiomatic to write return .{...};.
• Logging adds a new line by default, so you don't usually need to write \n like here: log.debug("event: {}\r\n", .{event});.

Please tell me if something doesn't make sense, I'll be sure to fix it!

What formatter did you use? I use prettier for markdown files and it did the formatting of this table automatically.

I used this one:

Should I revert that formatting?

[rockorager]

Yeah, let's stick with what prettier outputs. Thanks

This file should be renamed Cell.zig I believe

[tensorush]

Oh, yeah, will do

Thanks! A couple comments left inline. I appreciate it! Always like to have it be more idiomatic :)

The \r\n in the logs was for when the terminal is in raw mode (IE if you are logging but not redirecting stderr), you'll need the \r to get everything back to column 0. But generally logging should be redirected so I'm good with removing those.

Huh....seems like the file rename isn't here?

[tensorush]

Yeah, had to do a git mv to properly rename it. It's there now.
