proj: add prettier

[unional]

Once we have some code, I would like to add prettier to the tool chain so that it will automatically format your code.

So funny that we don't have it with so much config files =) But I am up to work on it with you!

[unional]

I don't have it because I personally have not used it.
So when adding it in I need to figure out the configurations so that it would fight with the particular linting rules that I use, and not contradicting with the guidelines I have here:
https://github.com/unional/typescript-guidebook

Tried Prettier and don't like it so far.
It creates contradicting rules so that VSCode can't format the code to satisfy those rules automatically.
For example,

import { createPluginCommand } from 'clibuilder'

export const scanCommand = createPluginCommand({
  name: 'scan',
  description: 'scan source files for strings to translate',
  run() { },
})

Prettier wants run() { } to be run() {},
but wants { createPluginCommand } to remain with space.

@unional I know Deno use other styler. Let me check if I can find which one

[venikman]

Hm can't find it. Only what I have found: https://deno.land/manual/tools/formatter
But I know they replace prettier with other formater... or we can try to write in Deno and use build in formatter

[unional]

Very likely Deno does use that default formatter.

It's the same approach as in Go and Rust. It's good to be opinionated by the language is that way. :)
