What is the problem we are trying to solve here?
The `/` path in our Ember app leads to the `discovery.index` route but
we actually don't render anything on that route leading to a blank page
if the Ember app were to transition to it which is what was happening
when a user adds a custom sidebar section link with the `/` path.
What is the fix there?
Instead of generating a link for the `discovery.index` route when
creating the sidebar section link, we detect if the Ember route is
`discovery.index` and change it to the `discovery.${defaultHomepage()}`
route instead.
Why this change?
Before this change, we were doing a partial match when checking for
existence. This is a source of flaky tests because a chat message with
text `this is a message` will match any substring like `message` or `a`.
What does this change do?
This change removes the partial match and instead opts for the
`exact_text` option instead.
Some sites have a large number of categories and fetching the category
IDs or category topic IDs just to build another query can take a long
time or resources (i.e. memory).
Our existing PluginOutlet system allows theme/plugin developers to easily insert new content into Discourse.
Another common requirement is to **replace** existing content in Discourse. Previously this could be achieved either using template overrides, or by introducing new content via a PluginOutlet and then hiding the old implementation with CSS. Neither of these patterns are ideal from a maintainability or performance standpoint.
This commit introduces a new mode for PluginOutlets. They can now be used to 'wrap' blocks of content in core. If a plugin/theme registers a connector for the outlet, then it will be rendered **instead of** the core implementation. If needed, outlets can use `{{yield}}` to render the core implementation inside their own implementation (e.g. to add a wrapper element).
In this 'wrapper' mode, only one connector can be registered for each outlet. If more than one is registered, only one will be used, and an error will be printed to the console.
To introduce a new PluginOutlet wrapper, this kind of thing can be added to a core template:
```hbs
<PluginOutlet @name="site-logo" @defaultGlimmer={{true}} @outletArgs={{hash title=title}}>
<h1>This is the default core implementation: {{title}}</h1>
</PluginOutlet>
```
A plugin/theme can then register a connector for the `site-logo` outlet:
```hbs
{{! connectors/site-logo/my-site-logo-override.hbs }}
<h2>This is the plugin implementation: {{@outletArgs.title}}</h2>
```
Care should be taken when introducing new wrapper PluginOutlets. We need to ensure that
1) They are properly sized. In general it's preferable for each outlet to wrap a small amount of core code, so that plugin/themes only need to re-implement what they want to change
2) The `@outletArgs` are carefully chosen. It may be tempting to pass through lots of core implementation into the outletArgs (or worse, use `this` to pass a reference to the wrapping component/controller). Doing this will significantly increase the API surface area, and make it hard to refactor core. Instead, we should aim to keep `@outletArgs` to a minimum, even if that means re-implementing some very simple things in themes/plugins.
Previously we were using 'mouseup', which meant that if you started the click inside, and then dragged to outside the modal, it would still close. This kind of dragging action is common when selecting text, and having it close the modal can be very frustrating.
Simply switching to a 'click' listener doesn't totally solve the problem, because when a click event involves dragging from one element to another, the browser will fire the event on "the most specific ancestor element that contained both elements". For modals, the most specific common ancestor was still the `modal-middle-container`, which would cause the modal to close.
Therefore, this commit sets the modal containers to have `pointer-events: none`, and sets up the click listener on the `.modal-backdrop` element, which is **adjacent** to the modal in the DOM. That means that click events fired on any ancestors of the modal will not accidentally trigger closure.
This would cause an error when deleting the original message of a thread, due to the non existing `last_message`. This fix is implemented using the null pattern.
Note this commit is also using this opportunity to unify naming of null objects, `Chat::DeletedUser` becomes `Chat::NullUser`, it feels better to have a name describing what is the object, instead of a name describing why this object has to be used, which can change depending on cases.
This is an aesthetic change. Currently, if one of the scores involved in the reviewable score explanation is negative, we display it as: + -value. This changes that.
I also made an attempt at converting the component into GJS format. This is done as a separate commit.

Follow-up to 477a5dd371
The `digest_suppress_tags` setting is designed to be a list of pipe-delimited tag names, but the tag-based topic suppression logic assumes (incorrectly) that the setting contains pipe-delimited tag IDs. This mismatch in expectations led to the setting not working as expected.
This PR adds a step that converts the list of tag names in the setting to their corresponding IDs, which is then used to suppress topics tagged with those specific tags.
While very fast and powerful staged threads forces a lot of gymnastic and edge cases. This patch adds a new service `Chat::CreateThread` and uses it to create a thread unconditionally when a user replies to a message in a threading enabled channel. If the user actually doesn’t send a message we will have a thread with no messages which has no important impact and could even be periodically cleaned if necessary.
Note that this commit also moves message actions to .gjs as it was the original goal of this PR to correctly check for staged thread to show the menu or not.
