PERF: Add index on topic_id and created_at to posts table (#22818)
Why this change?

In `PostDestroyer#make_previous_post_the_last_one` and
`Topic.reset_highest`, we have a query that looks something like this:

```
SELECT user_id FROM posts
WHERE topic_id = :topic_id AND
      deleted_at IS NULL AND
      post_type <> 4
      #{post_type}
ORDER BY created_at desc
LIMIT 1
```

However, we currently don't have an index that caters directly to this
query. As a result, we have seen this query performing poorly on large
sites if the PG planner ends up using an index that is suboptimal for
the query.

This commit adds an index to the `posts` table on `topic_id` and then
`created_at`. For the query above, PG will be able to do a backwards
index scan efficiently.

DEV: Cache summarization strategy results. (#22230)
Updates the interface for implementing summarization strategies and adds a cache layer to summarize topics once.

The cache stores the final summary and each chunk used to build it, which will be useful when we have to extend or rebuild it.

FIX: Video thumbnails can have duplicates (#21681)
* FIX: Video thumbnails can have duplicates

It's possible that a duplicate video or even a very similar video could
generate the same video thumbnail. Because video thumbnails are mapped
to their corresponding video by using the video sha1 in the thumbnail
filename we need to allow for duplicate thumbnails otherwise even when a
thumbnail has been generated for a topic it will not be mapped
correctly.

This will also allow you to re-upload a video on the same topic to
regenerate the thumbnail.

FEATURE: Add new don't feed the trolls feature (#21001)
Responding to negative behaviour tends to solicit more of the same. Common wisdom states: "don't feed the trolls".

This change codifies that advice by introducing a new nudge when hitting the reply button on a flagged post. It will be shown if either the current user, or two other users (configurable via a site setting) have flagged the post.

DEV: Replace #pluck_first freedom patch with AR #pick in core (#19893)
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.

There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.

Loïc Guitaut ec2ed5b7f6 FIX: Delete reviewables associated to posts automatically
Currently we don’t have an association between reviewables and posts.
This sometimes leads to inconsistencies in the DB as a post can have
been deleted but an associated reviewable is still present.

This patch addresses this issue simply by adding a new association to
the `Post` model and by using the `dependent: :destroy` option.

FEATURE: Show live user status on inline mentions on posts (#18683)
Note that we don't have a database table and a model for post mentions yet, and I decided to implement it without adding one to avoid heavy data migrations. Still, we may want to add such a model later, that would be convenient, we have such a model for mentions in chat.

Note that status appears on all mentions on all posts in a topic except of the case when you just posted a new post, and it appeared on the bottom of the topic. On such posts, status won't be shown immediately for now (you'll need to reload the page to see the status). I'll take care of it in one of the following PRs.

FEATURE: Generic hashtag autocomplete lookup and markdown cooking (#18937)
This commit fleshes out and adds functionality for the new `#hashtag` search and
lookup system, still hidden behind the `enable_experimental_hashtag_autocomplete`
feature flag.

**Serverside**

We have two plugin API registration methods that are used to define data sources
(`register_hashtag_data_source`) and hashtag result type priorities depending on
the context (`register_hashtag_type_in_context`). Reading the comments in plugin.rb
should make it clear what these are doing. Reading the `HashtagAutocompleteService`
in full will likely help a lot as well.

Each data source is responsible for providing its own **lookup** and **search**
method that returns hashtag results based on the arguments provided. For example,
the category hashtag data source has to take into account parent categories and
how they relate, and each data source has to define their own icon to use for the
hashtag, and so on.

The `Site` serializer has two new attributes that source data from `HashtagAutocompleteService`.
There is `hashtag_icons` that is just a simple array of all the different icons that
can be used for allowlisting in our markdown pipeline, and there is `hashtag_context_configurations`
that is used to store the type priority orders for each registered context.

When sending emails, we cannot render the SVG icons for hashtags, so
we need to change the HTML hashtags to the normal `#hashtag` text.

**Markdown**

The `hashtag-autocomplete.js` file is where I have added the new `hashtag-autocomplete`
markdown rule, and like all of our rules this is used to cook the raw text on both the clientside
and on the serverside using MiniRacer. Only on the server side do we actually reach out to
the database with the `hashtagLookup` function, on the clientside we just render a plainer
version of the hashtag HTML. Only in the composer preview do we do further lookups based
on this.

This rule is the first one (that I can find) that uses the `currentUser` based on a passed
in `user_id` for guardian checks in markdown rendering code. This is the `last_editor_id`
for both the post and chat message. In some cases we need to cook without a user present,
so the `Discourse.system_user` is used in this case.

**Chat Channels**

This also contains the changes required for chat so that chat channels can be used
as a data source for hashtag searches and lookups. This data source will only be
used when `enable_experimental_hashtag_autocomplete` is `true`, so we don't have
to worry about channel results suddenly turning up.

------

**Known Rough Edges**

- Onebox excerpts will not render the icon svg/use tags, I plan to address that in a follow up PR
- Selecting a hashtag + pressing the Quote button will result in weird behaviour, I plan to address that in a follow up PR
- Mixed hashtag contexts for hashtags without a type suffix will not work correctly, e.g. #ux which is both a category and a channel slug will resolve to a category when used inside a post or within a [chat] transcript in that post. Users can get around this manually by adding the correct suffix, for example ::channel. We may get to this at some point in future
- Icons will not show for the hashtags in emails since SVG support is so terrible in email (this is not likely to be resolved, but still noting for posterity)
- Additional refinements and review fixes wil

DEV: Rename secure_media to secure_uploads (#18376)
This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality.

This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site.

Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing.

This also keeps compatibility with the `secure-media-uploads` path, and changes new
secure URLs to be `secure-uploads`.

Deprecated settings:

* secure_media -> secure_uploads
* secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails
* secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb

FEATURE: Overhaul email threading (#17996)
See https://meta.discourse.org/t/discourse-email-messages-are-incorrectly-threaded/233499
for thorough reasoning.

This commit changes how we generate Message-IDs and do email
threading for emails sent from Discourse. The main changes are
as follows:

* Introduce an outbound_message_id column on Post that
  is either a) filled with a Discourse-generated Message-ID
  the first time that post is used for an outbound email
  or b) filled with an original Message-ID from an external
  mail client or service if the post was created from an
  incoming email.
* Change Discourse-generated Message-IDs to be more consistent
  and static, in the format `discourse/post/:post_id@:host`
* Do not send References or In-Reply-To headers for emails sent
  for the OP of topics.
* Make sure that In-Reply-To is filled with either a) the OP's
  Message-ID if the post is not a direct reply or b) the parent
  post's Message-ID
* Make sure that In-Reply-To has all referenced post's Message-IDs
* Make sure that References is filled with a chain of Message-IDs
  from the OP down to the parent post of the new post.

We also are keeping X-Discourse-Post-Id and X-Discourse-Topic-Id,
headers that we previously removed, for easier visual debugging
of outbound emails.

Finally, we backfill the `outbound_message_id` for posts that have
a linked `IncomingEmail` record, using the `message_id` of that record.
We do not need to do that for posts that don't have an incoming email
since they are backfilled at runtime if `outbound_message_id` is missing.

FEATURE: Promote polymorphic bookmarks to default and migrate (#16729)
This commit migrates all bookmarks to be polymorphic (using the
bookmarkable_id and bookmarkable_type) columns. It also deletes
all the old code guarded behind the use_polymorphic_bookmarks setting
and changes that setting to true for all sites and by default for
the sake of plugins.

No data is deleted in the migrations, the old post_id and for_topic
columns for bookmarks will be dropped later on.

FEATURE: Polymorphic bookmarks pt. 3 (reminders, imports, exports, refactors) (#16591)
A bit of a mixed bag, this addresses several edge areas of bookmarks and makes them compatible with polymorphic bookmarks (hidden behind the `use_polymorphic_bookmarks` site setting). The main ones are:

* ExportUserArchive compatibility
* SyncTopicUserBookmarked job compatibility
* Sending different notifications for the bookmark reminders based on the bookmarkable type
* Import scripts compatibility
* BookmarkReminderNotificationHandler compatibility

This PR also refactors the `register_bookmarkable` API so it accepts a class descended from a `BaseBookmarkable` class instead. This was done because we kept having to add more and more lambdas/properties inline and it was very messy, so a factory pattern is cleaner. The classes can be tested independently as well.

Some later PRs will address some other areas like the discourse narrative bot, advanced search, reports, and the .ics endpoint for bookmarks.

FEATURE: use canonical links in posts.rss feed (#16190)
* FEATURE: use canonical links in posts.rss feed

Previously we used non canonical links in posts.rss

These links get crawled frequently by crawlers when discovering new
content forcing crawlers to hop to non canonical pages just to end up
visiting canonical pages

This uses up expensive crawl time and adds load on Discourse sites

Old links were of the form:

`https://DOMAIN/t/SLUG/43/21`

New links are of the form

`https://DOMAIN/t/SLUG/43?page=2#post_21`

This also adds a post_id identified element to crawler view that was
missing.

Note, to avoid very expensive N+1 queries required to figure out the
page a post is on during rss generation, we cache that information.

There is a smart "cache breaker" which ensures worst case scenario is
a "page drift" - meaning we would publicize a post is on page 11 when
it is actually on page 10 due to post deletions. Cache holds for up to
12 hours.

Change only impacts public post RSS feeds (`/posts.rss`)
