Here is a breakdown of the changes that will be implemented in this PR.
# Widgets -> Glimmer
Obviously, the intention of the todo here is to convert the header from widgets to glimmer. This PR splits the respective widgets as so:
### widgets/site-header.js
```mermaid height=200
flowchart TB
A[widgets/site-header.js]
A-->B[components/glimmer-site-header.gjs]
```
### widgets/header.js and children
```mermaid height=200
flowchart TB
A[widgets/header.js]
A-->B[components/glimmer-header.gjs]
B-->C[glimmer-header/contents.gjs]
C-->D[./auth-buttons.gjs]
C-->E[./icons.gjs]
C-->F[./user-menu-wrapper.gjs]
C-->G[./hamburger-dropdown-wrapper.gjs]
C-->H[./user-menu-wrapper.gjs]
C-->I[./sidebar-toggle.gjs]
C-->J[./topic/info.gjs]
```
There are additional components rendered within the `glimmer-header/*` components, but I will leave those out for now. From this view you can see that we split apart the logic of `widgets/header.js` into 10+ components. Breaking apart these mega files has many benefits (readability, etc).
# Services
I have introduced a [header](cdb42caa04/app/assets/javascripts/discourse/app/services/header.js) service. This simplifies how we pass around data in the header, as well as fixes a bug we have with "swiping" menu panels.
# Modifiers
Added a [close-on-click-outside](cdb42caa04/app/assets/javascripts/discourse/app/modifiers/close-on-click-outside.js) modifier that is built upon the [close-on-click-outside modifier](https://github.com/discourse/discourse/blob/main/app/assets/javascripts/float-kit/addon/modifiers/close-on-click-outside.js) that @jjaffeux built for float-kit. I think we could replace float-kit's implementation with mine and have it in a centralized location as they are extremely similar.
# Tests
Rewrote the existing header tests ([1](https://github.com/discourse/discourse/blob/main/app/assets/javascripts/discourse/tests/integration/components/widgets/header-test.js), [2](https://github.com/discourse/discourse/blob/main/app/assets/javascripts/discourse/tests/integration/components/site-header-test.js)) as system tests.
# Other

- Converted `widgets/sidebar-toggle.js` to a gjs component
- Converted `topicFeaturedLinkNode()` to a gjs component
