Issue:
CSS optimization workflow parity during development (inlining `@import` statements)
## Summary
CSS supports referencing other CSS files using `@import` statements
```css
/* theme.css */
@import "../../node_modules/prism-themes/themes/prism-nord.css";
```

During production builds, Greenwood will inline these statements as part of the CSS optimization phase, but why not also do this during development?  Well...

## Details
The principal use case here is that [`@import` is not supported in Shadow DOM](https://github.com/WICG/construct-stylesheets/issues/119#issuecomment-588352418), so if you do, you will get an error like this in the browser

and thus unresolved `@import` paths

You can of course use our PostCSS plugin + [postcss-import](https://www.npmjs.com/package/postcss-import) and this will happen in development and production, but as stated, this already something Greenwood does during production so why not at least "backport" some of this behavior during development, if at minimum to provide a consistent development vs production experience.

----

Misc observations coming out of https://github.com/ProjectEvergreen/www.greenwoodjs.dev/pull/74
1. if we optimize when serving dev, then do we need `shouldOptimize`? - seems like no
1. should we make it optional since it is not standard behavior?
    - we _were_ doing it for production...    - make it optional and / or ignore certain operations in dev mode
1. Should we avoid any excess operations? (though really, once you turn it into an AST, the heavy lifting is really already there), like
    - minification - dev tools can format I think?
    - hashing - moderately expensive, but not really needed either way (use `fs` etc)
1. need to handle inline optimization bundle mapping edge case (see https://github.com/AnalogStudiosRI/www.analogstudios.net/pull/98)
1.  Seems `staticServer` is using `shouldServe` lifecycle, which at least explains unexpected prebundling, which we means we don't actually decouple plugins from server hosting...  (relates a a need / idea around standalone server, which I should also track)
    - yeah `npx http-server ./public` breaks
    - `npx http-server` loads all the content just fine, nowstandard resource plugins needed.  So do we even need resource plugins for staticStatic

## Related Issue
resolves #1257 

## Summary of Changes
1. Support inlining `@import` statements in development (too)
1. This also does all production optimizing too during development
1. Refresh PostCSS plugin README
1. Update styles and assets docs

## TODO
1. [x] Update test cases based on outcome of this being default (albeit) documented behavior
1. [x] Certain test cases will depend on #1259 being merged
1. [x] ~~figure out how to get `outputDir` from configuration~~ - not needed, its not configurable anyway
1. [x] ~~looks like development optimization strips `content` in one test case?~~ - looks to be an issue with [**csstree**](https://github.com/csstree/csstree/issues/179)

1. [x] we should probably be optimizing one-offs... (but how do we run `async` plugins inside a sync AST walker 🤔 )
  
## Questions
1. [x] does this need `outputDir` available in _loader.js_? - yes!
1. [x] Should we make it optional since it is not standard behavior?  Is this juice worth the squeeze? - not for now, since it brings a lot of immediate value
    - we _were_ doing it for production...
1. [x] Should we avoid any excess operations? (though really, once you turn it into an AST, the heavy lifting is really already there), like - not for now, but we can easily make it optional if it becomes an issue down the road, plus parity between dev and build environments is pretty important
    - minification - dev tools can format I think?
    - hashing - moderately expensive, but not really needed either way (use `fs` etc)
1.  [x] Somewhat related, but `staticServer` is using `shouldServe` lifecycle, which was giving some unexpected results when running `yarn serve` and seemed to be bundling even when we weren't using (this kind of relates a a need / idea around standalone server, which I should also track) - put into my personal backlog
    - yeah `npx http-server ./public` breaks
    - `npx http-server` loads all the content just fine, nowstandard resource plugins needed.  So do we even need resource plugins for staticStatic
1. [x] add a tracking item for `content` with octal values? - https://github.com/ProjectEvergreen/greenwood/discussions/1238#discussioncomment-10225611
